26-year-old Mark Thomas was supposed to be a friend - at least on Facebook. Instead, police say he broke into the woman's home.
"It's serious charges when you kick somebody's door in and steal their belongings. That's a serious crime," Upper Darby Police Superintendent Michael Chitwood said.
The two had chatted on Facebook.
The woman posted that she had a cell phone for sale, and police say Thomas claimed he wanted to buy it.
"Their relationship was formed over Facebook. She's lucky that's all he did," Chitwood said.
Saturday afternoon the two met up at the woman's home near 69th Street. Thomas was supposed to buy a phone from her.
As the two walked toward a cell phone store to activate the phone, police say he told her he forgot his sunglasses and ended up going back.
When the she got back to her house, the door was kicked in. Two rings and a cell phone were gone.
Action News went to Thomas' home to ask him about the allegations. Someone peeked through the blinds, but never opened the door.
Most people we spoke to say they aren't surprised by what happened.
"If I don't know you, why would I want to know your business? Why would I want you to know my business? It's access to your family pictures," Janel Chaughnessy of Aldon said.
"You may have something that you're looking for and the other people's intention may be different than yours," Hector Rivera of West Philadelphia said.
This time police were able to get everything back to the woman and she wasn't hurt. But Chitwood says this should be a reminder to us all.
"You're opening yourself up. You're allowing people into your life that maybe shouldn't be allowed in your life. It's a danger."
Thomas is out on a $10,000 unsecured bond.
