UPDATE: SFPD has questioned and cleared the suspect of any wrong-doing.

The following warning has been circulating throughout various parenting lists regarding a lurker at Mountain Lake Park in the Richmond. As always, keep an eye on your kids!

Please help spread the word to people you know in this neighborhood. I have seen this man 2 times at the lower playground at MLP. He does NOT have children and pretends like he does and is there to do pull ups. He takes pictures of the kids with his phone. He drives a silver PT cruiser and wears sunglasses. He takes pictures of BOTH boys and girls. He looks for kids that don't have care givers near by. I have not confronted him, but take Scout and stand next to him. He gets nervous and puts his phone away and eventually leaves. I personally believe that given the chance he might engage the kids and who knows what could happen....

The friend who sent this to SFist said it best:

I have absolutely no idea if this is real or not, but am fascinated by it just the same. What if it is just some random guy doing pull-ups? What kind of person actually drives a silver PT Cruiser? Apparently, a "bad man" does...

If you see this suspicious person at Mountain Lake Park, call the Richmond District Police Department non-emergency number at 415-666-8000 (415) 553-0123. Calling 311 will also get you there, or to any district in which you encounter a pervy lurker. This makes us wonder if that law about adults not being allowed in parks playgrounds without a child is ever enforced.
