Calgary police are investigating after five houses in southeast Calgary were hit by vandals.

Police say the houses were spray painted with various symbols and graffiti, and were all located in the Midnapore and Sundance areas.

"Potentially some of the symbols have been identified as swastikas and the others are still undetermined as to the nature of their meaning," said Sgt. Jason Bobrowich with the Calgary Police Service.

"Whenever there are any type of symbols that have negative connotations, we will engage and utilize our crime prevention team and diversity resources team."

Police say the homes were vandalized sometime between late Friday night and early Saturday morning.
