A Los Angeles Police Department officer was arrested for stabbing a man at a bar in Upland while off duty. 

According to a statement from LAPD, the officer, 55-year-old Arthur Contreras, who is a 28-year veteran with the department, was arrested on Wednesday but subsequently released. He has since been placed on administrative leave. 

"The Los Angeles Police Department's Internal Affairs Division initiated an administrative investigation, which is being conducted simultaneously with the pending criminal case," the statement said.

"The department is fully cooperating with the District Attorney's Office and the Upland Police Department's investigation relating to Contreras' alleged criminal conduct," the LAPD statement said. 

The LA Times says that Contreras was released after posting $40,000 bail and has an initial appearance at the Rancho Superior Courthouse in Rancho Cucamonga on Friday.
