A Washington State Patrol trooper arrested Tacoma City Councilman Ryan Mello Sunday night during a drunken driving stop.

Trooper Guy Gill says Mello was pulled over for lane violations and voluntarily submitted to field sobriety tests after the trooper smelled alcohol.

Gill told KING (http://bit.ly/10zUpCN) Mello cooperated through the process and did not identify himself as a councilman.

The Pierce County prosecutor's office will decide whether to file a charge.
