POLICE are warning residents to be on their guard after two distraction burglaries took place just 30 minutes apart.
In the first, a man in his 60s answered the door to a woman who claimed she was from the council and needed to check the drains.
While they were out of sight at the rear of the property, it is believed a man entered the house and stole money and a set of car keys.
It happened close to Mallatratt Place, Mansfield, at about 1.20pm on Wednesday.
At 2pm, an elderly woman in her 90s, who lives in the Netherfield Lane area, Church Warsop, was targeted.
She answered the door to two women, again claiming they needed to check the drains.
One of the callers took her to the back of the house to discuss the drains while it is believed the other woman made her way into the house. She made off with money and a bank book.
It is believed the incidents are linked.
Detective Sergeant Rick Ellis, of Mansfield CID, said: "The victims of these thefts have been left distressed and shaken up.
"Do not let anyone into your home who you have not made a prior appointment with. Anyone who is a legitimate caller will have identification."
Anyone with any information should contact Detective Sergeant Rick Ellis at Mansfield CID on the non-emergency number 101 ext 3464.
