BEVERLY HILLS—Alfred Poirier, a former deputy chief of the Beverly Hills Fire Department, was arrested on September 21 on suspicion of stalking and vandalism, according to the Beverly Hills Police Department. The 63-year-old Santa Clarita resident was taken into custody shortly before 8 p.m. He was released on $150,000 bail shortly after midnight.

Poirier spent 36 years with the Los Angeles Fire Department, where he rose to chief deputy of emergency operations. He joined the Beverly Hills Fire Department in 2022 as its second-in-command and retired in April. In Beverly Hills, he oversaw emergency response operations and the safety and training division.

Police said Poirier is accused of repeatedly posting computer-generated images at city buildings. They have not said what the images showed or how they were put up. Under California law, putting unauthorized material on someone else’s property can count as vandalism, along with defacing or damaging it.

A stalking charge means police believe Poirier repeatedly harassed a specific person and made a credible threat meant to make that person fear for their safety. Authorities have not said who the alleged victim is or whether it is a city employee. Police Capt. Kevin Orth declined to give further details, citing the ongoing investigation.

No charges have been filed yet. If charged and convicted, Poirier could face up to a year in jail on each count as misdemeanors, or up to three years on each if prosecutors file them as felonies.
