A broken nose and two bare buttocks were the tally when windscreen cleaners took things a bit far in New Plymouth yesterday.

Stunned motorists called police after a fracas between two squeegee bandits on the corner of Liardet and Courtenay streets during rush-hour traffic at 5.40pm.

Senior Sergeant Thomas McIntyre said police arrested two of the group for fighting.

"In their words, they said they were ‘testing their friendship'," he said. "This resulted in one of them sustaining a broken nose."

They will appear in the New Plymouth District Court today.

Minutes later, police were called back to the corner for the buttocks incident.

"A woman driver has been approached by a female cleaner, and politely declined her offer of a windscreen clean.

"The cleaner has then pulled down her pants and mooned her," Mr McIntyre said.

"The driver was disgusted at what she saw."

The mooner had pulled up her pants and disappeared by the time police returned.

Mr McIntryre said police and the public were getting sick and tired of the nuisance caused by the cleaners. He urged the public to alert police if they had concerns about behaviour.
