A MYSTERY door knocker has been terrorising vulnerable and elderly people in sheltered accommodation for over a decade.

Residents from Chelmsford Court, near Perry Wood, claim someone has been knocking on their doors, walls, and windows three or four times a week during the middle of the night.

But the perpetrator has never been caught.  

Byrn Roberts, age 75 moved to Chelmsford Court after being attacked near the railway arches in Worcester in 2007.

But Mr Roberts said he has fallen victim to antisocial knocking for the past 15 years. 

Mr Roberts said: "You can't have a decent night's sleep, I've had to change my lifestyle because of the knocker and I tend to take a nap in the afternoon but it can make you feel like you're in a prison.

"You are always on edge because of it.

"We don't know who it is, but it must be someone who is active in the winter."

Not only that but the ex-postman said he has been struggling to sleep for the past few weeks due to a hernia.

"It is a little disheartening because it happens at around 3.15am and you're not up at that time in the morning to check quickly enough. 

"Due to my hernia, I can only sleep on one side and it's difficult for me to get up.

Patricia Agar, councillor, said: "This has been a long-standing problem, people are being victimized and someone is knocking on their doors and walls and then running away. 

"They're obviously very nimble because they are able to get away very quickly.

"The residents don't know who it is and they're frightened and scared. 

"Residents go to Chelmsford Court because it is a sheltered and safe place." 

"It's sheltered accommodation that is being invaded all the time. 

"There are about four residents who are experiencing it."

A police spokesperson, said “We’ve spoken to members of the Safer Neighbourhood Team for Battenhall and Nunnery, who are not aware of an ongoing issue with ‘knock door run’ at Chelmsford Court. 

"However, we have yet to speak to everyone on the team as some are not on duty until later this week. 

"Once we have spoken to the rest of the team and established the facts we will be in a position to provide further comment.”

A spokesperson from Platform Housing said: "We're sorry to hear this is currently an issue for our residents.

"This has been raised previously and our on-site team have explored various ways possible to help in both identifying the perpetrator and reassuring the residents.

"Our residents' safety is of paramount importance and we will revisit this issue with them."
