SAN FRANCISCO (CBS/BCN/AP) -- Hossein Nayeri and Jonathan Tieu, who escaped an Orange County jail last week, were arrested Saturday morning in San Francisco after a witness reported seeing one of the suspects and the vehicle they were driving.
Just before 9 a.m., the citizen flagged down officers near Golden Gate Park and pointed out a parked white van that looked like one believed to be stolen by a trio of inmates during their brazen jailbreak last week in Southern California.
Officers located a person who matched the description given by the witness near the corner of Waller and Stanyan streets.
As police approached the van, Hossein Nayeri -- whom officials have called the probable mastermind -- was captured after a short foot chase in the park near Kezar Stadium.
A stolen van the men were driving was located at Haight and Stanyan streets. Inside the van, officers discovered the second fugitive, 20-year-old Jonathan Tieu, hiding with ammunition but no gun, police said.
Officers detained Tieu and both escapees were taken into police custody.
"This is an excellent example of how the public can help SFPD keep this city safe -- a citizen saw a someone suspicious, notified an officer, which ultimately led to the apprehension of two armed and dangerous criminals who escaped from jail," Police Chief Greg Suhr said in a statement.
Prior to their apprehension Saturday morning, Nayeri and Tieu had been seen Thursday night in San Jose near The Alameda and Interstate Highway 880, according to the U.S. Marshals Service.
Nayeri and Tieu escaped from the Orange County Central Men's Jail in Santa Ana on Jan. 22.
The two men and one other -- 43-year-old Bac Duong -- escaped from jail on Jan. 22.
Duong surrendered on Friday to a civilian in Santa Ana.
The three had been awaiting trial on separate violent felony charges, including murder, attempted murder, torture and kidnapping. Duong and Tieu have ties to street gangs that operate in the shadows of Orange County's thriving Vietnamese community.
Authorities still don't know the answers to a number of questions about the escape, including how the inmates got their hands on the sharp cutting tools necessary to hack their way through jail walls, where they had been hiding, and how Duong got back to Santa Ana after parting ways with the others.
The three inmates were housed together in a large module that held 65 other men, about half of whom were in custody for violent felonies.
In the early morning hours of Jan. 22, the trio sawed through a metal grate covering a plumbing tunnel, then crawled through piping to reach the jail's roof. There, they pushed aside barbed wire and used a rope made of bedsheets to rappel four stories to the ground.
Jailers did not realize the men were missing for 16 hours.
On Thursday, authorities arrested a woman who taught English at the jail. Nooshafarin Ravaghi, 44, gave Nayeri a paper copy of a Google Earth map that showed an aerial view of the entire jail compound, sheriff's spokesman Lt. Jeff Hallock said.
She was booked on suspicion of being an accessory to a felony and was being held pending a court appearance set for Monday.
It wasn't clear if she had a lawyer.
Ravaghi and Nayeri also exchanged "personal and close" handwritten letters, but Hallock could not say if the two were romantically involved.
The day after the escape, Duong responded to a Craig's List ad for the white GMC van and stole it during a test drive, authorities said. The trio likely lived in the van during their week on the lam.
Saturday's arrests happened near Golden Gate park, an area popular with both tourists and the homeless.
Vergel Dalusung said he saw three police cars surrounding a white van that was parked across the street from a McDonald's, just outside a Whole Foods Market. He only saw police handcuff one man and put him in a patrol car, and it happened very quickly, he said.
"And that's when I stopped looking because I figured it was all taken care of," Dalusung said.
Hutchens said the men's capture now clears the way for an intense probe into how they were able to escape. That will mean examining where systems, policies and procedures may have failed.
No staff members have been disciplined or removed, she said, adding that any investigation would take time.
"We do not want another escape from an Orange County jail, I can tell you that," the sheriff said. "We're going to do everything we can in our power — and it's not enough to say, 'Gee, we have an old jail, it's a challenging place.'"
Built in 1968, the jail that housed the men holds about 900 inmates. It was the first breakout from the facility in nearly 30 years.
Duong, a native of Vietnam, has been held since last month on charges of attempted murder and assault with a deadly weapon.
Tieu is charged with murder and attempted murder in a 2011 gang shooting. Nayeri had been held without bond since September 2014 on charges of kidnapping, torture, aggravated mayhem and burglary.
The three will soon be transported back to the same jail from which they escaped, Hutchens said.
"I can tell you they won't be together," she said.
