LAKEVILLE — A Twin Cities man has been cited for misdemeanor domestic assault after witnesses say he punched his son at a basketball tournament.

Fifty-two-year-old Steven Wilson of Eagan was booked into the Dakota County Jail after the altercation, which took place Saturday at Lakeville Senior High School.

Witnesses told officers that nearby parents stepped in when they saw Wilson punch his son in the face after his team lost. The teen did not require medical attention.

Wilson posted bond and was released from jail.

Wilson deferred comment Monday to his attorney, who did not immediately return a phone message.
