A man accused of trying to stab a junior high football coach in an unprovoked attack as the coach was sitting in his car in Manoa Wednesday has been charged.

Roberto Raymundo Smith, 41, of Salt Lake, is being held on $25,000 bail after being charged on a felony count of unauthorized entry into a vehicle.

Additional counts of second-degree assault, possessing a butterfly knife, first-degree terroristic threatening and three traffic warrants, are pending investigation.

Paul Brown, 46, said his truck was stopped at a traffic signal at University Avenue and Kaala Street about 6:30 p.m. Wednesday when he was approached by a stranger who tried to punch and stab him.

Brown, who is also a restraint instructor at the Kapolei juvenile detention home, managed to pin the man and disarm him with the help of another coach whose vehicle was behind his. The coaches were leaving Mid-Pacific Institute following a practice by the Pac-Five intermediate football team.
