FRAMINGHAM — A Massachusetts man is facing an assault charge for allegedly hitting a town hall custodian on the back of the head with a roll of toilet paper because he was angry the cleaning man was whistling while he worked.

Framingham police say 55-year-old Allen Kerner was in town hall Wednesday using the bathroom. The custodian, who didn't realize anyone was in the restroom, whistled as he replenished toilet paper rolls.

The custodian told police he was in a stall when he was struck. Kerner yelled at him about whistling and fled. The custodian pursued him, and Kerner was apprehended by police outside.

Police tell The MetroWest Daily News that Kerner will be summoned to court to face an assault and battery charge. A phone number for Kerner could not immediately be located.
