Vulnerable pensioners living in a sheltered housing complex say their lives have been made hell by a persistent knock-a-door-run prankster who has been tormenting them for 15 years.
People living in Chelmsford Court in Worcester suffer nightly knocking up to four times a week.
The mystery cherry knocker has reportedly been banging on the same residents' windows and doors for the last decade-and-a-half - but has yet to be tracked down.
Residents are now in talks with bosses about installing CCTV cameras outside the sheltered accommodation to catch them red handed.
Retired postman Bryn Roberts, 75, revealed he started being targeted not long after moving into the complex in 2008.
