A 20-year-old man was arrested Tuesday after he and two other suspects robbed a man at gunpoint in his apartment last month.

Christopher Jack, 20, now faces one count of aggravated robbery. He remains in the Bexar County Jail. His bail has yet to be set.

According to his arrest affidavit, Jack and two other suspects robbed a man at his apartment on Jan. 2, 2017. It is unclear where the apartment is located.

The victim told police Jasmine Ramirez, another suspect in the case, came to his apartment looking for the victim's girlfriend, Alisyn.

The victim invited Ramirez in to wait for Alisyn's return, and five minutes later, Jack and another unidentified victim knocked on the door.

Jack and the other suspect were armed with guns, and one of them hit the victim in the head with what appeared to be a Mac 10 Uzi hand gun, according to the affidavit.

The suspects then allegedly demanded the victim gather all his electronics and place them on the living room sofa.

After he had done so, the victim noticed Ramirez was no longer in the apartment. Jack and his accomplice told the victim to go to the back of the apartment while they left, according to the affidavit.

One of the victim's neighbors caught the license plate number of the vehicle in which they fled. Officers tracked it back to Ramirez's aunt's house. Ramirez was later arrested in connection with the robbery.

He was later arrested and booked into jail on an aggravated robbery charge.
