Police have renewed their appeal for information in their hunt for vandals who have smashed the windows of an elderly couple's home multiple times.
Officers were most recently called to an address in West Park Road, Maidstone after a stone was thrown through a window at around 3.20am on Friday, April 12.
The couple's son, Scott Morgan, desperately appealed for information about the offenders earlier this month - offering a £500 reward.
He also released shocking CCTV footage of two people repeatedly smashing car and house windows in a campaign of harassment lasting more than a year.
Investigators are specifically trying to trace a man seen wearing a three-quarter length coat which was longer at the back and had the hood up, dark trousers and dark shoes.
District Commander for Maidstone, Chief Inspector Ray Quiller said: "We have launched an investigation into this incident and are linking it to three previous damages in the same location over the last year.
"My officers have completed house to house enquiries, forensic checks and have reviewed any possible CCTV opportunities.
"However, it is very important for anyone who may have seen the incident, or spotted a man with a long coat acting suspiciously to contact us."
Anyone with information can call Kent Police on 01622 604100, quoting reference 46/69523/19.
