PASADENA >> No one was hurt when a man threw some type of “homemade pyrotechnic device” into a Cheesecake Factory restaurant in Old Pasadena on Thursday evening, authorities said.
The attacker remained at large following the incident, which took place just after 6 p.m. at the restaurant at 2 W. Colorado Blvd., Pasadena police Lt. Art Chute said.
The restaurant was crowded with diners when a man opened the front doors and tossed in the device, which exploded, the lieutenant said.
No injuries or significant damage to the building were reported.
“Officers immediately entered the restaurant and evacuated customers and employees and located a detonated homemade pyrotechnic device,” Pasadena police said in a written statement. “The Los Angeles County Sheriff’s Department Bomb squad responded to the scene and rendered the device safe.”
The device was described as a seemingly homemade pyrotechnic device containing gunpowder, Chute said.
The man who threw the device was last seen fleeing the area on foot.
The motive in the bizarre attack remained a mystery.
“Pasadena police detectives are currently handling the investigation and out of an abundance of caution, the federal authorities have been notified,” according to the statement.
Police described the man as a Latino or Middle Eastern man, about 6 feet tall, of thin build, with a heavy beard. He wore all black clothing and a black beanie.
