VERNON, Conn. � Vernon police said they arrested a man who was dressed as a ninja and waving nunchucks while yelling about wanting to beat up U.S. Sen. Joe Lieberman.

The man, 30, was charged Sunday with breach of peace. Police said he was brought to Rockville General Hospital for a psychiatric evaluation and later released.

Authorities said they received several emergency calls about the man, who witnesses say was standing at the corner of Route 83 and Regan Road at about 11 a.m.

Officers said they pulled out bean bag and taser guns, and the man became polite and cooperative.

The man couldn't be reached Monday. He has no public phone listing, and it's not clear whether he has a lawyer.
