Police are investigating at least a dozen complaints from residents in Middlefield about a door-to-door salesman selling children's books.
"He has a permit in Middlefield, but he's worn out his welcome," Middlefield Resident Trooper Eric Kelly said Friday.
According to Kelly, the salesman has been "very pushy" with residents and is wanted for questioning.
He said the salesman will often ask residents if they know where he can find homes with children, in order to sell his product.
The salesman may be traveling in the Durham area as well, but does not have a permit to do so, according to Kelly.
Residents are not in any danger, but anyone who encounters the salesman is asked to call Troop F immediately at 860-399-2100. Town Hall has also received several complaints, but residents are urged to call police.
Police are also asking anyone with a description of the vehicle the salesman is traveling in to contact them.
