SAN GABRIEL – Police arrested a woman Tuesday afternoon for leaving an infant inside a vehicle that was parked in the sun for about half an hour, authorities said.

Yue Gu, 50, of Monterey Park, was booked on charges of child endangerment, said San Gabriel police Lt. Darren Perrine.

Perrine said Gu, the child’s grandmother, parked her car in a restaurant parking lot in the 500 block of East Valley Boulevard at about 3 p.m. to use a rest room. The temperature inside the car had reached 111 degrees, he said.

A security guard heard the 2 month old’s screams from inside the car and called police, he added. The baby was transported to a hospital and has since been released.

“We make several arrests a year for this,” Perrine said
