Don’t Mess with Heisenberg

A man is in jail after breaking into 'Breaking Bad' star Brian Cranston's car. One item stolen: The script to the AMC show!

Twenty-nine-year-old Xavier Macafee was arrested last week and made his first court appearance yesterday. He's accused of stealing Cranston's script, iPad, a shoulder bag (man purse?) and 'other miscellaneous items.'

The cops say the car was broken into on Dec. 20 while it was parked at Sandia Park in New Mexico, while shooting scenes around town for the show. They also say the items stolen have not been found but they are still investigating.

Lawyer up Xavier, Walter White is coming for ya!

'Breaking Bad' is going into it's filth and final season on AMC.
