Castronovo, 49, was arrested in Salem, Oregon on Sunday morning (14Jun15) after allegedly fighting with a woman. He was arraigned on Monday (15Jun15) and charged with fourth-degree assault and menacing.

According to court papers filed by Marion County Deputy District Attorney Jean Kunkle, the drummer knowingly caused physical injury to the woman involved in the altercation.

Castronovo is free after posting $20,000 (£13,300) bail and he is set to return to court on 30 June (15) for a plea hearing.

The drama has prompted his Journey bandmates to seek a replacement, while their regular drummer takes care of his legal woes.

The band announced the line-up change ahead of a Hollywood Bowl show on Saturday (20Jun15) in a statement, which reads: "Journey has made the decision to have Omar Hakim play drums for the band's upcoming U.S. concerts (Hollywood Bowl on Saturday, June 20 and the Stadium of Fire in Provo, Utah on Saturday, July 4), as well as the band's Canadian tour (July 6 - August 3), due to Deen Castronovo's pending issues."

Castronovo, a former member of rock act Bad English, joined Journey in 1998, while Hakim is best known for his work on David Bowie's Let's Dance, Sting's The Dream of the Blue Turtles and Dire Straits' Brothers in Arms albums. He also worked with jazz fusion group Weather Report and Miles Davis.
