San Antonio police detained three men in connection with a hold-up late Monday on the city's West Side.
Police said the trio walked into Danny's Food Mart in the 200 block of Castroville Road at 11:15 p.m. and flashed a gun. Moments later, they got away with $400 and the cashier's keys.
SAPD launched its Blue Eagle helicopter to search the area near the store and found one of the men hiding behind a house on Chihuahua, where officers also found the cashier's keys and a gun.
The two other men, both in their late teens or early twenties were questioned, but police did not say whether they would be charged.
