Officers are investigating three fires in the Bransholme area of Hull which we think may be connected.
They were started on 3 Oct at derelict shops at Roebank arcade, a derelict building on Soffham Close, and in a wheelie bin on Stockleigh Close.
No-one was hurt in the blazes but damage was caused to the buildings particularly to the shops at Roebank arcade.
Humberside Police are asking for witnesses to come forward, or anyone who may know who is responsible to contact them.
