SEATTLE — Seattle police say they arrested a man who crashed an 8-year-old child’s party, ate several pieces of pizza and took two balloon animals.

Parents told police they asked the 28-year-old man to leave after he joined the children’s party at Green Lake on Wednesday evening. However, police say the shirtless, shoeless man refused and got into a “very heated” exchange with the families at the party. The families called police.

In a release on their website, police say the man appeared to be under the influence of a “potent relaxant of some kind.”

Officers first checked to see if the man needed medical attention, then arrested him for investigation of theft.
