A woman has taken to US classifieds website Craigslist to find a man that impregnated her at a Motorhead gig.

In an advert titled 'Did we hook up at the Megadeth/Motorhead concert?', a woman said that she randomly met a man whilst in the crowd at the metal gig in Chicago.

She added that their connection was so instant that they rushed to the bathroom to express their new found friendship in a quick burst of physical activity.

However, it seems the bout of passion ended up impregnating the woman - and she is wondering if the unidentified man would like to now become "part of the child's life". The post read:

"Me: Blue hair, silver tube top, fishnets, Knee high black biker boots. You: Red mohawk, black pentagram gauges, viper piercings. I was grinding on you in the pit, then we went to the bathroom, and got f***ed up."

She concluded: "Anyway I'm pregnant. It's yours. Contact me if you want to be part of your child's life."
