Police have released surveillance video of multiple suspects involved in two separate assaults and robberies in the Bronx.

The first incident left a man beaten unconscious on Sept. 14, inside a Walton Avenue and E. 183rd Street apartment building.

Police say the 48-year-old victim was attacked by the suspect who followed him into the lobby of the building before punching him several times and stealing his cellphone and wallet.

The second incident happened on Sept. 18 and involved four suspects, a woman and three men, who attacked a 34-year-old man with sticks at the foot of a stoop on Walton Avenue and E. Fordham Road.

Police say the victim fought off the attackers but not before they got away with a bag of food. 

Police ask anyone with information in either case to call Crime Stoppers at 1-800-577-TIPS.
