RESEDA – Cops identified the man arrested today for allegedly impersonating a police officer and robbing at knifepoint an elderly couple of $100 inside their Reseda townhouse as Dennis J. Bryley. Bryley was booked into the Los Angeles County Jail on robbery charges and held on $1.1 million bail. The robbery occurred about 8 p.m. yesterday in the 7500 block of Corbin Avenue, when a man dressed in police-type clothing knocked on the couple’s door and inquired about an auto accident the couple was involved in earlier in the day, said Los Angeles police Officer Jason Lee. When one victim grew suspicious and asked the suspect for identification, he allegedly pulled out a knife and robbed the couple of $100 before fleeing on foot, Lee said. No one was injured in the robbery, Lee said. The man was arrested early today, according to a lieutenant at the LAPD’s West Valley Station. His name was not immediately released. The man usually is the one who confronts people on sidewalks while the woman stays in the car, described as a black foreign model with four doors. The heists have occurred in the following locations: Police said it did not appear that the man involved in last night’s stick-up was the same as a man involved in similar robberies involving crooks posing as law enforcement in the San Fernando Valley. In those cases, police were searching for a couple who has been impersonating sheriff’s deputies, detaining San Fernando Valley pedestrians and making off with cash. The man and woman have targeted four people in the Valley since July 19, swiping about $2,000, police said. None of the incidents have been violent, but the suspects – complete with khaki get-ups, badges and caps that say “sheriff” – pat down victims and go through their pockets, taking cash and whatever else they can find. The man is described as white, 30, between 5 feet 5 and 5 feet 9 and weighing 180 pounds. The woman is described heavyset, and 5 foot 4 with blond hair.

If there’s ever a question, ask to see a badge, picture ID and where the cop works. “It makes it difficult for the public because people want to cooperate with police,” said Los Angeles police Detective Dan Jaramillo, who is investigating the cases. Los Angeles County sheriff’s deputies wear uniforms with green pants and tan shirts, Deputy Maribel Rizo said. They wear badges on their chests along with a name plate and a gun belt. They usually drive black-and-white patrol cars with lights and sirens. Undercover officers usually present their badges and will show photo IDs if anyone has questions, she said. Deputies never seize property unless the individual is put under arrest before they are frisked, she said.
