A bogus caller who duped an 85-year-old out of his life savings and a thief who posed as an electricity worker to rob a 97-year-old woman, are being targeted in a citywide crime crackdown.
As part of a new hard-hitting initiative, police promised to leave no stone unturned as they waged war on the scourge of bogus callers.
This strong message came as the force launched one of its most comprehensive bogus crime operations yet, coinciding with a national campaign, to snare the criminals who prey on the elderly and vulnerable.
They are urging anyone who suspects bogus callers or workmen may be operating in their area to report them.
As officers point out, the motivation for the criminals is always the same - to steal money and possessions from the most vulnerable people in our communities.
It is a crime which has a profound affect on its victims, often sparking a serious decline in health, and fills most of us with disgust.
And police officers working across Glasgow are no exception.
By working with housing associations, care providers, neighbours and banks, officers are identifying more victims.
Victims who have been previously targeted are closely monitored and some given surveillance equipment to catch the culprits if they are brazen enough to visit them again.
But police say they are also committed to driving these "despicable" criminals out of town and, by calling on the help of Trading Standards and Her Majesties' Revenue and Customs, they will make life difficult for people who travel door to door trying to rob elderly people.
Efforts have been particularly focused in the Shettleston area, which is a known target for travelling con men because of its proximity to the M8 and M74.
There have been 14 reports of bogus caller crime in the area since April.
Communities Inspector Arlene Smith told the Evening Times: "I have been a police officer for 18 years and there is nothing that gets me more motivated than bogus callers.
"Most police officers will tell you it is one of the most despicable crimes they have to deal with."
At the launch of the latest crackdown, early yesterday morning, a team of officers left Shettleston Police Station to hand deliver letters to those known to be involved in "doorstep crime" in the East End of Glasgow.
The hard-hitting warnings state that officers will use "all lawful means to disrupt such behaviour" and add that the recipient may also be subject to a financial investigation by HMRC and the Department for Work and Pensions.
It adds: "Please note that individuals who move around acquiring custom (traders who also travel) require a Pedlar Certificate, the absence of which is an arrestable offence."
Inspector Smith explained that officers are adopting an 'Al Capone approach' - if they can't catch the con men in the act, they will tackle them for other offences, including tax evasion, just like US authorities did with the famous mobster in 1930s Chicago.
As part of the operation, Jobs and Business Glasgow and the city council's Land and Environmental Services department were also out yesterday working to tidy up overgrown gardens in Sandyhills. Con men are known to target such home in the belief that elderly or vulnerable people live there.
Nearby, on Tollcross Road, a "no entry for bogus callers" sign also flashed red to warn drivers.
Officers in the South Side also staged a road block, pulling over vans on Dumbreck Road to make sure the occupants were legitimate tradesmen.
Superintendent Martin Cloherty, who is leading the crackdown, said all reports of bogus crime are now being dealt with by detectives.
He said: "These abhorrent crimes have a devastating impact on the quality of life of the victims and can lead to a decline in their health and leave them scared to trust others."
Mr Cloherty said he feels everyone has a part to play in beating the scourge of bogus- caller crime, and added: "As well as appealing to elderly people not to let these criminals in, we are urging people to be vigilant on behalf of more vulnerable family members and neighbours and tell us when they become suspicious.
"Your door is the last line of defence for your property - you would never willingly let anyone steal from you, so don't give them the opportunity by letting them inside."
Ms Smith added: "With this operation we have had to get into the mind set of the criminals.
"They are devious but we are approaching this from every possible angel.
"The message is, if you come here and target our elderly people we will find you and bring you to justice."
