LOS ANGELES (CBSLA) — A $15,000 reward for information was offered Friday to track down a serial robber who pretends to need help moving in order to gain a victim’s trust, then holds them at gunpoint for their cash.

The LAPD says they began investigating a series of robberies involving a lone man in a truck in May of 2018. His method was to approach pedestrians on the street and offers them $50 for help in moving furniture.

Once the victim agreed, they get into the truck and would be driven to a residential area, where they would then be held at gunpoint for all their cash.

Detectives say the robber targeted people in Arleta, Pacoima and Panorama City, coming out of check cashing businesses.
