A 28-year-old man arrested in connection with a series of armed robberies involving United States Postal Service carriers in Los Angeles’ San Fernando Valley faces federal charges.

The suspect, arrested by the Los Angeles Police Department last month and identified as Andranik Naghdalyan, was charged Thursday with robbery of a mail carrier, according to the United States Attorney’s Office. The federal charge carries a maximum sentence of 25 years in federal prison.

The robberies dating from Dec. 3 occurred in Valley Village, Studio City and Sherman Oaks. Heists also were reported Jan. 31 and Feb. 21 and 22.

In each case, a man with a firearm approached the carriers and demanded their postal keys and electronic scanners. The robber then left the scenes in a white Lexus sedan, police said.

In the Dec. 3 heist, the suspect allegedly demanded the carrier’s mail keys, but carrier pretended to faint and fell on top of the key, according to the federal criminal complaint. The carrier told authorities the man tried to reach for the key and a brief scuffle ensued. The carrier’s USPS scanner was stolen, prosecutors said.

On Feb. 22, following a robbery in the 5400 block of Ethel Avenue in Sherman Oaks, police located and arrested the suspect during a traffic stop.

Evidence was recovered from the car that linked the man to the crimes, police said.

Authorities are attempting to determine whether there are more victims. Below are the locations and dates of the crimes.
