POLICE have reassured people after an increase in the number of nuisance telephone calls.
A message was sent out to Neighbourhood Watch members in Tring on Wednesday.
PCSO Thomas Montgomery said: “The Tring Neighbourhood Team have been made aware of some residents receiving telephone calls in the past few weeks.
“The caller is on most occasions not saying anything just holding the line open and then disconnecting after several seconds. On occasions they have spoken a few words and then disconnected.”
But Mr Montgomery told people not to worry and, if a resident receives a nuisance call, they should hang up the phone and contact their service provider.
He added: “Should anyone have concerns and would like to speak to the Neighbourhood Team, please feel free to contact us.”
The police non-emergency number is 0845 33 00 222.
