A 16-year-old Muskego student accused of giving a "wedgie" to his former girlfriend at school is facing juvenile charges of fourth-degree sexual assault.

The girl, 15, told authorities that the boy pushed her up against a locker, put his hand down the back of her pants and pulled her thong up above the waistline of her pants, the police report released Wednesday says. The boy also touched the girl's buttocks, the report says.

She told him to stop at least three times and said that the incident was both painful and embarrassing, the report says.

After the assault, according to the report, the boy said, "Now I got some action."

The boy told police that since he had dated the girl in the past, he thought it was OK to do what he did.

Assistant Superintendent Robert Rammer said that the offense did not warrant expulsion but that the student was suspended for five days.

"It's unfortunate," Rammer said. "It was an isolated incident. It was immediately dealt with."

Police were called to Muskego High School, W183-S8750 Racine Ave., at about 6:30 p.m. Sept. 24 for an alleged assault, Capt. Paul Geiszler said.

The girl told police that she was getting ready for band practice at about 5:30 p.m. and that when she came out of the locker room, she was confronted by the 16-year-old boy, the report says.
