A Nottinghamshire Police spokesman said: “This man drives around in a white Ford Transit van targeting elderly people by turning up saying he has fixed either their roof or guttering.
“This male then makes demands of payment for works not carried out.”
He is described as white, tall, aged in his late 20s with stubble an “unusual hair cut a little like a dark Mohican-style” and speaking with a British accent
The spokesman said: “Nottinghamshire Police are investigating these incidents and progressing the cases however they ask that the community are extra vigilant and report anything suspicious to the police either by 101 or 999 if a crime is being committed.
“Please share and help us reach out to our elderly members of the community.”
