Update, 8:40 p.m. The man who was arrested Friday in Berkeley after a CHP chase has been identified as Carlos Kuceja, 28, according to jail records.

Authorities say Kuceja dropped a live grenade out of his stolen car during the police pursuit.

He was arrested on suspicion of felony evading — wrong way driver and disregarding safety — as well as vehicle theft, possessing a destructive device and other crimes, according to jail records.

Kuceja is being held at Santa Rita Jail on $390,000 bail and is scheduled for arraignment Tuesday at Wiley Manuel Courthouse, records show.

Berkeley police arrested Kuceja in mid-April on suspicion of prowling, according to public records. He has no charged criminal cases in Alameda County, according to court records.

Update, 6:10 p.m. A suspect who threw a grenade out of his car was arrested in Berkeley on Friday after leading CHP officers on a pursuit from Oakland, authorities report.

The incident began around 3:30 p.m. when officers on the CHP's crime suppression team spotted a stolen car near Cerrito Avenue and 38th Street in North Oakland, the California Highway Patrol said.

When officers tried to stop the driver, he fled, authorities said.

The CHP chased him for 15 minutes, ending up in North Berkeley.

"As the suspect vehicle was passing the intersection of Martin Luther King Jr. and Rose Street, the driver threw a bag out of the window," according to the CHP. "An officer not involved in the pursuit immediately stopped and secured the bag."

Inside, the officer found what authorities believe was a live grenade, the CHP said.

"Officers immediately closed traffic at that location and began evacuating people from the area. The suspect continued fleeing for another two blocks before turning down a dead end street and ultimately surrendering to officers," according to the CHP.

Authorities arrested the driver, whose name was not immediately available.

The University of California Police Department bomb team responded to the scene and took possession of the device.
