A woman was arrested Friday afternoon when she brought a handgun into a courthouse in Manteca.
Lan Chen, 43, is facing firearms-related charges, the San Joaquin County Sheriff's Office said.
The sheriff's office said Chen had an unloaded Beretta 9mm pistol in a satchel when she went through the security screening process at about 2:20 p.m. Friday at the San Joaquin County Superior Court's Manteca Branch. A magazine loaded with four bullets was next to the gun.
Chen also was carrying $10,583 in cash in her purse, the sheriff's office said.
Security guards called San Joaquin County sheriff's deputies, who took Chen into custody without incident.
