PHILADELPHIA, Pennsylvania (Reuters) -- A man described by authorities as a known sexual predator was chased through the streets of South Philadelphia by an angry crowd of Catholic high school girls, who kicked and punched him after he was tackled by neighbors, police said Friday.

Rudy Susanto, 25, who had exposed himself to teen-age girls on as many as seven occasions outside St. Maria Goretti School, struck again on Thursday just as students were being dismissed, police said.

But this time, a group of girls in school uniforms angrily confronted Susanto with help from some neighbors, police said.

When Susanto tried to run, more than 20 girls chased him down the block. Two men from the neighborhood caught him and the girls took their revenge.

"The girls came and started kicking him and punching him, so I wasn't going to stop them," neighbor Robert Lemons told The Philadelphia Inquirer.

Susanto was later treated for injuries at a local hospital. Police said he would be charged with 14 criminal counts including harassment, disorderly conduct, open lewdness and corrupting the morals of a minor.
