Real estate investor finds home booby-trapped with swinging knife

A real estate investor claims a home he was scoping out came with an unadvertised surprise — a stairway booby-trapped with a swinging knife.

Ekrem Uysaler said he and his team were looking at the home in January when one of his co-workers saw a small line on the home's staircase.

According to US broadcaster WCAU-TV, Mr Uysaler stopped his construction manager from heading up the stairs and recorded video as they pulled the staircase line with a spare rod.

Pulling the line triggered a fast-moving, downward-swinging crutch from above the staircase.

Taped to the end of the crutch was a large knife pointing right to where a person's head would have been walking up the stairs.

The Philadephia man said he has never encountered something like this before. He says "It's like 'Home Alone' ... Philly style."
