MILWAUKEE -- Milwaukee police said a person responsible for a bizarre prank may be in serious danger.

Someone climbed a 1,200 foot TV tower in Lincoln Park, belonging to the local CBS station and hung a dummy on it.

It took police a while to confirm it was a dummy and not a body. Not only was the prank a crime, but it was also extremely dangerous.

Police said the person who did it was probably exposed to microwave radiation and needs to be checked at a hospital. ”My understanding is that radiation poisoning may mimic flu-like symptoms. They may think that they just have the flu, but they may have radiation poisoning, so we need whoever is responsible for this. They need to get themselves to a hospital or to a doctor and seek immediate medical attention,” said Anne Schwartz with the Milwaukee Police Departmant.

Police said the radiation is only a threat to those directly involved.

A worker in a protective lead suit was sent up the tower to bring down the mannequin.
