An individual is now in police custody, and security measures have been implemented after the suspect attempted to get access to Romulus Middle School in Southeast Michigan, a school official said. 

The Romulus Police Department said in a social media post that it was called to the school building on Wick Road about 9:53 a.m. Tuesday, on a report of an "active shooter." School employees had seen a man "brandishing a handgun attempt to enter the school's main doors and immediately instituted a lockdown. There were reports of shots fired," police said.

Arriving officers found a 44-year-old man near the main entrance of the school and took him into custody. A handgun was also recovered at the scene, police said.

"To ensure accurate information is shared and to help prevent the spread of rumors or misinformation, I want to clarify that an individual attempted to gain access to the middle school while brandishing a firearm. The individual is now in police custody, and there is an active investigation underway," Romulus Community Schools board president Porsche Laster said in a social media post that morning.

Laster said that Superintendent Dr. Benjamin P. Edmondson issued an automated phone call to parents, relating "the information that can be shared at this time." 

Nobody can enter Romulus Community Schools without going through the secretary. There's a secured door. So there was a gentleman at the door with a gun, and she saw that. She immediately called 911," Edmondson said. 

Families were asked to allow students to stay at school for the time being, although a CBS News Detroit crew did notice some parents arriving on campus mid-day.  

Police say the investigation is ongoing in regards to the suspect's motive or intentions, adding, "there is no ongoing threat to the school or the community."

"Your best nightmare is what happened. Everything worked according to how it should have worked," Edmondson said. 

In the meantime, the police department said it wanted to commend the Romulus Community Schools employees "for their quick recognition of danger and immediate notification to 911. Their professional and timely actions may have prevented this incident from becoming much worse."

In a statement posted on social media, Michigan Gov. Gretchen Whitmer said her office has been in contact with local officials in Romulus regarding the incident. 

Police ask that anyone with information that can help in the investigation contact Detective Sergeant Otter at 734-942-6857. Callers may remain anonymous.

Romulus Middle School houses grades 6-8 for the district. Students at Romulus Community Schools resumed classes Monday after their winter break. 

Edmonson said that counselors are being brought in on Wednesday for students and staff who are traumatized by what happened.  

The Michigan school safety tipline program is known as OK2SAY. The program began 10 years ago and provides steps that anyone can use, 24/7, to report potential harmful or criminal activities involving students or a school campus.
