UNION CITY -- A wanted parolee armed with a pipe was shot and killed by Union City police on Monday night, the agency said.

Officers were called to the 4200 block of Saturn Way around 8:30 p.m. when a disturbance was reported, police said. While at the residence, they learned that one of the people involved was on parole and wanted on an arrest warrant for resisting and deterring an officer by using threats, force or violence, police said. They did not have details about the incident that resulted in the warrant.

According to Cmdr. Jared Rinetti, officers made contact at the residence and entered the home. But the parolee was confrontational and threatened police with a pipe he was holding.

When the threats continued and the person didn't comply with orders, one of the officers fired his gun. The parolee was taken to a hospital, where he was pronounced dead. Police have not identified him pending notification of his relatives.

Officials did not say if the parolee lunged at the officers.

Police provided no information regarding the officer who fired but said he would be placed on administrative leave, per department policy. Union City police and the Alameda County Sheriff's Office are investigating the shooting.

It was the second time in less than two months that Union City police have been involved in a fatal shooting. Police shot and killed Vergel Ricafrente Worrell on Aug. 31 after Worrell was "acting incoherent and screaming profanities" while stumbling around a neighborhood in the 32600 block of Kenita Way. That shooting came six months after two officers shot and killed 26-year-old Amos G. Smith after police said he pointed a gun at them while trying to flee a traffic stop on Dyer Street on March 2.

Police asked anyone with information about Monday's shooting to call 510-471-1365. Anonymous tips can be left at 510-675-5207.
