EVERETT, Wash., Sept. 13 (UPI) -- A Washington state man is being investigated for first-degree assault after allegedly attacking a guitarist for singing a song he didn't like, officials say.

The 33-year-old Mount Vernon, Wash., man, whose name was not released, has "a potential mental health issue," prosecutors said. He was being held on $25,000 bail, The (Everett, Wash.) Daily Herald reported Monday.

The suspect jumped on stage with a knife while a band performed Friday during the Mukilteo Lighthouse Festival. The guitarist, who suffered minor cuts to his neck, used his guitar to fend off the attack.

The man later told police he didn't approve that the band was singing what he thought was a song about a baby or a girl.

Andrew Alsdorf, a deputy prosecutor, argued for a $50,000 bail, given the suspect's mental state.

"There is a potential mental health issue going on, but the overwhelming concern is for the safety of the community," Alsdorf said in court.

No mention of what the song was.
