In the wake of a theft at Macy's in San Mateo, California, the quick response and cooperation between local law enforcement and the store's Loss Prevention agents led to the swift arrest of Antonio Aguilar Barrios, a 26-year-old resident of San Mateo.

The robbery occurred yesterday, at 7:34 p.m., when Barrios is alleged to have stolen hundreds of dollars worth of merchandise from Macy's, located at the Hillsdale Shopping Center, without making any attempt to pay for the items. 

According to the San Mateo Police Department, upon leaving the store, Barrios was confronted by a Loss Prevention agent, whom he threatened with a stun gun before fleeing the scene.

In response to the report of the robbery, multiple officers searched the area and located a suspect matching Barrios' description within minutes of the crime. A witness confirmed that Barrios was the culprit, leading to his arrest and the recovery of the stolen merchandise.

He was charged with second-degree robbery and is currently being held at San Mateo County Jail, as reported by the San Mateo Police Department.
