The wheelchair-bound pensioner is paralysed with fear since the two anonymous notes landed on her Prestwick doormat.

A sinister sender has creepily written: ‘We are watching you, get yourself back to where you came from or your house will be blown up.’ In a second note, the vulnerable 60-year-old is pathetically called a ‘grass’ for phoning the police about the first one.

The Advertiser is backing calls for South Ayrshire Council to get Margaret out of Wallace Court and into sheltered housing.

Margaret said: “I need a safe house. I can’t go on like this. I’m scared to go out and am a recluse in my own home. I am absolutely terrified and keep the door locked at all times.

“When I saw the letters I just completely broke down. I am worried they will hurt me or my son.” The initial poison pen letter came a couple of months ago with the second arriving within the last two weeks.

Disturbingly the latter note revealed how the sender had been watching the address, saying the cops had been spotted at her door. The police are on the hunt for the scrawling culprit — and have now seized the letters, which were stamped and came via Glasgow.

The mother-of-one only moved into Wallace Court in February and has desperately pleaded to be relocated due to a catalogue of problems with her accommodation.

But the intimidation has now made it completely unbearable.

The disabled widow who has lung disease COPD, diabetes, angina and rheumatoid arthritis only relocated to Prestwick so she could have a ramp.

But the new place has been plagued with problems, including leaky radiators, a bare patch of plaster and no room for her wheelchair to manoeuvre.

Margaret who moved from Cavendish Place in Troon, would even be willing to do without a ramp just to escape.

She lost her husband Robert eight years ago.

She said: “I just want to be back in Troon in sheltered housing where I know people. I am not eating because of the anxiety and my carers are worried sick. The only time I leave this house is for hospital appointments and admissions. I thought getting a ramp was a new start for me and would give me independence.”
