(AP Photo/Paul Sancya) Cops in Wasilla have arrested Sherry Johnston, the soon-to-be grandmother of Bristol Palin's baby, on felony drug charges, the Anchorage Daily News reports. Johnston is the mother of 18-year-old Levi, the boyfriend of Bristol. The two gained the spotlight when it emerged during Sarah Palin's campaign that they were expecting. It's not clear what kind of drugs were involved, but the charges suggest she was manufacturing or dealing them. Johnston's arrest was part of "an undercover narcotics investigation" that had been going on for "a while," say state troopers. She was booked and released on $5,000 bond. Bristol Palin's baby is due tomorrow, says her grandfather Chuck Heath. It will be the Alaska Gov. Palin's first grandchild. (More Bristol Palin stories.) Report an error
