ST. PAUL, Minn. (AP/WCCO) — St. Paul police are investigating three recent stun gun attacks.

Investigators say the first attack happened Saturday night just north of Como Park Golf Course. A man out walking was assaulted by several males with a stun gun who took his keys.

Two other attacks happened Monday night. A man riding his bike was hit from behind by a vehicle and knocked to the ground. The suspects used a stun gun on the cyclist and stole his cellphone.

Later, a woman out jogging near Como Park Zoo and Conservatory was pushed to the ground by two men who assaulted her with a stun gun.

“Doesn’t make me feel safe at all,” said Como Park jogger Beth Shields. “Makes me think about running somewhere else.”

None of the victims could provide a detailed description of the suspects.

“I would probably avoid like riding alone in that area, like later in the evening,” said Como Park bicyclist Emily Weber.

Police are warning people to be careful in the areas where the assaults happened.
