A disgruntled boyfriend was sentenced to prison for attempting to sell his ex-property girlfriend's after she abandoned him and for firebombing a neighbor's Range Rover.

When his relationship with his former lover, Dr. Margit Szel, 70, ended, Graham Harmes, 69, began a five-month surveillance campaign against her.

On several occasions, he broke into her luxurious seaside home in Dorset, UK, to relocate or smash possessions and steal vital documents.

While Dr. Szel was away, Harmes superglued the locks and arranged for an estate agent to go over the house, take pictures, and list it for sale.

Jennet Bennett, Dr. Szel's next-door neighbor, saw Harmes damage her car and reported it to the police.

In retaliation, Harmes destroyed Bennett's £40,000 Range Rover by setting it alight in the middle of the night, causing an explosion outside her home.

At Bournemouth Crown Court, Harmes pleaded guilty to stalking, arson that was reckless as to whether life was endangered and witness intimidation.

Court Recorder Robert Weekes QC sentenced Harmes to four years and five months in prison, with the seven months spent in custody since October to be taken into account.
