A woman who bungled a bank robbery after getting so drunk cashiers could not understand her demands for £30,000 has been jailed for six years.

Margaret Kaid, 55, of Burnely, Lancashire, had dressed up as a purple-haired police crime scene investigator in a white boiler suit and gloves in the hope of escaping detection as she held up a city centre Yorkshire Bank.

However, she had guzzled so much vodka and 'cheap cider' in the build-up to the heist Kaid could barely her write her own threatening demands for £30,000 on pieces of paper which she passed to cashiers.

Kaid bungled the robbery of the Yorkshire Bank in Manchester after getting so drunk on vodka and 'cheap cider' that cashiers could not understand her demands for £30,000

Baffled staff were unable to read two scrawled notes she handed them until she slurred: 'Stop f..king around' and produced a third note saying: 'One of your customers will die' before plonking a kitchen knife on the counter.

Quick thinking officials at the Piccadilly Gardens branch in Manchester immediately pressed a panic button triggering a security alert and Kaid staggered out empty handed - inadvertently showing her face to CCTV cameras as she left.

She carried out another armed robbery moments later at a Santander bank just yards away and escaped with just £750 after giving up on passing threatening notes.

Kaid was jailed for six years after she admitted robbery attempted robbery and a further bungled raid at a Starbucks cafe carried out six days after the bank raids.

She also pleaded guilty to possessing an offensive weapon.

Manchester Crown Court heard the bank raids occurred within minutes of each other at about 5pm on May 25 after Kaid had been drinking and taking diazepam.

Prosecutor Miss Vanessa Thomson, said: 'She was in disguise or trying to conceal her appearance but it was fairly distinctive as she was wearing a white boiler suit and gloves.

'The clothing was like somebody would wear doing decorating work or a crime scene examiner. She was staggering and was under the influence of drink or drugs and one person said that she smelt like vodka and cheap cider.

'In the Yorkshire Bank she collected a withdrawal slip and went to a man who worked there and handed him the slip - but he was unable to read what was on it.

'She then handed another piece of paper but he struggled to read it again.. Eventually she said 'stop f..king around' and he could then see it said '£30,000'.'

Prosecutors said Kaid appeared at the counter with a withdrawal slip (left) with a message but the cashier was unable to read it. She then placed a knife on the counter (right)

Kaid produced another piece of paper which said: 'or one of your customers will die'.

Thomson added: 'She then placed a knife on the counter and another cashier realised what was happening.

'The defendant was aware of the security in place and said 'don't fire the fucking screens, don't touch the button' - but one of the staff pushed the button and the door was bolted. She left taking with her her knife and not taking anything in terms of money or proceeds.'

Kaid then staggered off to nearby Santander where she again produced the knife and said: 'give me what you have in the till, give me your money'.

The panic alarm was activated but Kaid escaped with £750 from an 'emergency fund' held at the bank.

The court heard the raid at Starbucks in Hanging Ditch, Manchester, occurred on May 31 with Kaid producing a knife and telling a female assistant: 'f**king turn around - open the f**king till.'

She fled empty handed when staff said the till couldn't be opened until a purchase was made and was arrested nearby.

In a statement, a cashier at the Yorkshire Building Society said: 'Because of what happened I feel my life had hanged quite seriously. It's made things worse when I've been at work and people walk in, I've not experienced something like this before and now I look at anyone as a potential robber.. I shouldn't have to look at our customers in this way.

'I now feel anxious and nervous being around people I don't know. I had to take time off work because of stress and anxiety. I was having thoughts of 'what ifs'. At the time I was studying for a law degree and had to take exams a short time after and felt my results were affected by what occurred.'

Kaid then left the Yorkshire Bank and went to a nearby Santander in Manchester to try again

An employee from Santander said: 'I thought I would be fine but then when I was sat on the counter I realised I was not fine. I was quite nervous of customers and couldn't do my job. She was the last person I expected to rob a bank. It's made me second guess people.'

The employee at Starbucks said: 'I'm anxious at work every time the door opens I look to see who it is. It was an older woman with a knife which makes it worse because I feel like I can't trust anyone. For the first week after it happened I couldn't leave the house and kept having panic attacks.

In mitigation for Kaid, defence lawyer David Bentley, said: 'Her mindset was not clear during the course of these offences it's not clear now what triggered the decision for her to act in the way she did but her judgement was blurred by the chemical influences she had consumed.

'What efforts there were to disguise herself she removed the hood and it was clear for all to see - this was highly unsophisticated. She has a blurred recollection of aspects of these offences and can't give a reason why she decided to commit them.'

Passing sentence the judge Miss Recorder Michelle Brown said: 'The use of a weapon aggravates the offences as well as the disguise, the fact you were probably under the influence of drink and drugs the fact there were a number of victims and the fact you caused serious psychological harm.
