Madison police arrested a 32-year-old Madison resident Saturday morning after knocking another man unconscious.
Deon T. Johnson punched a 33-year-old visitor from San Jose, Calif. on the 500 block of State Street, according to a Monday incident report by Madison Police Department Public Information Officer Joel DeSpain.
The suspect and victim did not know each other, according to the incident report. A detective saw the assault as he was driving down the street as part of the Downtown Safety Initiative, a 2007 effort to reduce violent crime in the downtown area. As the detective approached Johnson and the victim, Johnson attacked the victim, leaving him unconscious for five minutes.
Police are still investigating what initiated the attack.
Police arrested Johnson on charges for substantial battery, possession of cocaine and possession of marijuana. He has a hold on his probation, meaning he is not allowed any bail.
