AN OFFER from elusive street artist Banksy is being investigated as potential electoral fraud.

Banksy, famous for his satirical and politically-themed graffiti, is offering the prints of a new limited edition artwork to people who vote against the Tories in seats in and around Bristol formerly held by the party's MPs.

An announcement on his website says that a new Banksy piece will be released on June 9, the day after the General Election - a print of his famous "balloon girl", but with the red heart balloon replaced with the Union flag.

But Avon and Somerset Police said it had received a number of complaints about the offer and that it is investigating.

A statement on the force's Twitter account said: "We've received a number of complaints about an offer of a free Banksy print to people living in six Bristol constituencies in exchange for them voting in a certain way in the forthcoming election and we can confirm we're investigating the offer.

"It is a criminal offence under the Representation of the People Act 1983 for any voter to accept or agree to accept a gift or similar in return for voting or refraining from voting.

"Any person participating in an offer to receive a gift is at risk of being prosecuted."
