A man with six previous DUI convictions could end up with his seventh after police were called to a McDonald's in southern Delaware about a screaming customer.

On Friday at about 9 p.m., state police said, the McDonald's on Del. 24 in Millsboro flagged down a passing trooper, reporting that a customer was yelling and screaming from his vehicle.

Police said Levi D. Stilwell, 53, of Millsboro appeared drunk and "showed multiple signs of impairment."

They found that Stilwell had six previous DUIs, and charged him with a seventh, as well as failing to comply with taking photos and fingerprints.

Stilwell was held on $8,000 bond.
