Suspect identified after throwing unknown substance in Webber Pool, threatening others

Webber Natural Swimming Pool in Minneapolis is closed after a person put an unknown white substance into the water on Thursday.

On Friday, about two hours after Minneapolis Park Police asked for public assistance in identifying a man who was acting irrationally at the pool. In a later update, they said the man had been identified but did not provide the name of the person.

Police say they were called to the pool at 4:34 p.m. for an assault and learned that a man had placed a hand on a lifeguard and threatened to push the guard into the pool.

The suspect made other verbal threats and inappropriate comments to staff and pool visitors, police say.

Witnesses told police they saw the man put an unknown white substance into the pool, according to the police report.

The pool will remain closed as the Minneapolis Park and Recreation Board works to determine the best process for testing the water.
