An Allentown Police Department officer has been charged with allegedly pistol-whipping a man after a police chase last month, according to the Lehigh County district attorney.

Abviud Carvajal, 30, has been charged with aggravated assault and simple assault in the July 23 incident, District Attorney Gavin Holihan said. Carvajal surrendered to police Thursday and was released on $25,000 bail. He has a preliminary hearing on Aug. 26. He's been placed on administrative leave.

The alleged assault happened around 8 p.m. on July 23 at 13th and Pennsylvania streets in Whitehall Township.

According to Holihan and Allentown Police Chief Charles Roca, body and dash camera footage show Carvajal with his gun drawn, approaching Thomas Kravitz of Philadelphia after a chase through Allentown and into Whitehall Township.

Kravitz is allegedly seen in the video standing at the back of his truck with his hands raised and empty, ready to surrender, the DA and police chief said in a news release. They said another police officer was also detaining Kravitz at gunpoint.

Authorities alleged Carvajal struck Kravitz in the face with the muzzle of his gun. They said Kravitz was visible to Carvajal for "at least four seconds."

"From the body camera, it is clear that Kravitz was empty-handed and surrendering to officers," a news release says. "He remained standing with his empty hands over his head as Carvajal approached. … In the time that Kravitz was standing with his hands up, he made no motions that could be construed as threatening and there was no evidence that he was reaching for a weapon. Kravitz was knocked to the ground with injuries to his face."

The DA and police chief said the body and dash camera footage will not be released to the public. They claimed it's to "ensure Carvajal's right to a fair trial," according to the news release.

Carvajal is the only Allentown police officer charged in connection with the incident.

"This incident does not state or define the Allentown Police Department," Roca said. "Our officers show up day in and day out to do a good job, and my priority is to maintain public trust, to work to maintain public trust within our community and also to ensure accountability when things go wrong."

Kravitz was taken to a nearby hospital and treated. He was later arrested and charged with several crimes, including illegal possession of a firearm, fleeing from police and causing an accident while not properly insured.

Authorities said Kravitz led police on a chase after fleeing from his girlfriend's house on North 11th Street in Allentown.

Carvajal and other officers were called to the area after receiving a report of a threat involving a gun. A woman called 911, alleging her boyfriend made a threatening phone call and sent her pictures with a gun, the DA and police chief said in a news release.

Police identified a truck belonging to Kravitz and surveilled the area, authorities said. Police attempted to stop Kravitz after he arrived in the area. Kravitz allegedly fled the scene, hitting an Allentown cruiser in the process and leading to the police chase.

After a police chase through Allentown and into Whitehall Township, Kravitz crashed his truck at 13th and Pennsylvania streets, where the alleged assault happened, Holihan said.

Authorities said they found a .22 caliber handgun in the 1200 block of Whitehall Street. They believe Kravitz discarded the gun during the chase.

Kravitz remains in jail in Lehigh County awaiting a preliminary hearing.
