SMITHFIELD, R.I. — Police in Rhode Island say a drunk driver crashed his car into the vehicle of an officer on a DUI patrol.

Smithfield police say the officer was in his car writing a summons early Saturday when another vehicle rear-ended his cruiser, damaging both cars.

Police say the driver, Derek Lewis, of Pascoag, was charged with driving under the influence, refusal to submit to a chemical test and other offenses.

Lewis wasn’t hurt. The officer was treated for minor injuries.

Court records don’t list an attorney for Lewis.
