The NYPD needs help finding a total of three men after two people were assaulted and robbed in Morris Heights.
Investigators released surveillance images of the suspects in connection with the crimes back on Feb. 8 in front of 1963 Grand Concourse. 
According to police, one suspect approached a 51-year-old woman and grabbed her buttocks. When the victim tried to defend herself, they say the suspect punched her and took off with about $200. 
The same man, along with two others, allegedly attacked a man who witnessed the first robbery. The trio is accused of punching and kicking him before taking off with his phone.
