Police say a Los Angeles man posed as a photographer for Vibe magazine to lure women with promises of modeling opportunities and then sexually assaulted them.

Capt. Blake Chow said Wednesday that they are looking for 22-year-old Keith Nichols, a security guard from Compton, who is suspected of sexually assaulting four women.

Chow says Nichols told them they could be models for Vibe, but he had to measure them for "custom-fitted underwear" first.

Police say Nichols allegedly took out a measuring tape and then touched them sexually. The suspected crimes occurred in public places that were secluded and out of sight.

Chow says the women realized they had been conned when Nichols didn't returned their phone calls.
