MARIETTA, Ohio — A real weirdo cops have been hunting for two months has been arrested in Ohio for allegedly getting his kicks by squirting his semen out of a syringe onto women’s backsides as they walked around stores.

Police say Timothy Blake has copped to 12 separate instances where he masturbated in his car in shopping mall parking lots, filled a syringe with his semen, and then trailed women around stores and squirted it on them.

“The first report came in two months ago from a woman who had found this on her bottom and after cleaning it off in the bathroom had walked out to find him waiting and staring at her,” Washington County Sheriff Larry Mincks told the Parkersburg News and Sentinel. “She said he then took off and she followed him until he got in his truck and left.”

Horrified cops say they had been on the lookout for two months for the vehicle which Blake often drove, that sported an insignia from the oilfield company he worked for and had been captured by mall security cameras.

Upon his arrest, cops say Blake, who is married and has kids, shamefacedly admitted that he had started partaking in his weird fetish after finding out about it on the Internet and deciding to give it a try and discovering he liked it.

Blake has been charged with stalking. Authorities are asking that any other women who have been victims of Blake’s disturbing hijinks to file a report with police.
