A Gainesville man allegedly broke a former co-worker’s arms with a baseball bat and took the victim’s cellphone and wallet, according to authorities.

Christopher John Herrera, 18, was charged with aggravated battery and armed robbery in alleged connection to a Jan. 19 incident. He was arrested Thursday.

According to authorities, Alberto Venegas was waiting for a ride near Lamplighter Cove and Browns Bridge roads when a vehicle approached.

Herrera allegedly “exited the vehicle and demanded the victim to give him his wallet and cellphone,” according to authorities.

“After giving Herrera the items, the victim was struck multiple times by Herrera with a baseball bat,” Hall County Sheriff’s Office spokesman Deputy Chad Mann wrote in a news release.

Herrera allegedly dropped his own cellphone and fled the scene after a passer-by stopped to help Venegas.

“The image on the locked screen of the phone was identified by the passer-by as the subject that assaulted the victim,” Mann wrote. “The victim and Herrera had previously worked at the same company.”

The company was not disclosed.

According to the warrants, Herrera allegedly took $500. Venegas’ arms were broken, according to the warrants.

“Later that morning, Herrera filed a report that his cellphone had been stolen during an entering auto,” Mann wrote.

He faces an additional charge of falsely reporting a crime.

Herrera remained in the Hall County Jail on Tuesday.
