The NYPD is asking for help tracking down two suspects linked to a citywide pattern of headphone robberies.

Police say the moped-riding thieves struck on May 13 when they approached a 24-year-old man on Marcy Avenue in Brooklyn. The suspects punched and kicked him to the ground and took off with the suspect's headphones.

A few minutes later on McGuinness Boulevard, police say they repeated the pattern to a 27-year-old woman along with two different occasions in Manhattan.

All victims are expected to be OK.
