Action News spoke to one victim who says while this is unfortunate, he's thankful no one was hurt.
Tom O'Callaghan started his morning routine as usual on Wednesday, but couldn't make it to work when he found an unpleasant surprise.
"Get in my car and I look over, just thinking, 'Why is there glass everywhere?' Sure enough, my car got its window smashed. It was my car and another car next to it as well," he recalled.
O'Callaghan has lived in the Kingswood Apartments for more than a year. He says he's never faced this problem living there.
"You feel kinda helpless. It just feels a little bit like you got violated. It's really unfortunate. Again, no one got hurt, so that's the one good thing that comes out of this," he said.
O'Callaghan says in addition to his window being broken, some of his items were stolen from his car.
"They really didn't take anything from my car except the one bag I had in there, which was full of dirty clothes," he said.
Now, as he waits to get his window fixed on Monday, O'Callaghan and some others are contemplating moving.
"It's an epidemic, it really is. It happens everywhere. It really doesn't matter where," he said.
O'Callaghan had one final message to the thieves who stole from him and others across the area.
"Enjoy my dirty clothes. That's all I got for ya!"
The Upper Merion Police Department is asking that anyone with information on these incidents contact them at 610-265-3232.
