As he was being arrested Beant Singh threatened that he would be back to "handle what he started," according to deputies.

LATHROP, Calif. — A man was arrested Saturday after investigators said he threatened to shoot and kill his former coworkers at Dhaliwahl Trucking.

Beant Singh was recently let go from the company and was set to pick up his last paycheck. Instead, he showed up around 10:30 a.m. with a gun - pointing it at two people and firing one round into the ground, according to the San Joaquin County Sheriff's Office. No one was hit.

After being arrested, Singh threatened that he would come back and "handle what he started," deputies said. The Sheriff's Office has not named the company involved in Saturday's workplace violence.
