A 27-year-old man was arrested for allegedly impersonating a police officer and brandishing a handgun at two separate shopping centers in San Mateo on Sunday afternoon, police said.
Allen Grabovetsky was arrested after officers initially responded at 3:06 p.m. to the Hillsdale Shopping Center at 60 31st Ave. on multiple reports of a man with a gun in his waistband, according to police. Witnesses reported that the man had allegedly waved what looked like a black handgun at several people while saying he was an undercover police officer.
He fled before officers arrived, but police were able to obtain surveillance footage and shared it with the public, eventually leading to the identification of Grabovetsky as the suspect.
