The graffiti was painted on homes in Hitchin’s Hazel Court, Stuart Drive, Girons Close and The Avenue, with a garage and house in Ennismore Close in Letchworth also affected.

The unsolicited drawings – which are legally considered criminal damage – were first noticed between January 31 and February 3.
