BT has “strongly advised” against anyone interfering with its network after shoes were seen dangling from overheard cables in Bury St Edmunds.
Openreach, which is part of the BT Group, warned the behaviour could not only cause injuries, but also disrupt important services.
In recent weeks, shoes and trainers have started appearing over power and telephone wires in Bury, baffling residents in the attractive Suffolk town.
Incidents have been reported in Mustow Street, Northgate Street, Fornham Road, Mildenhall Road, Southgate Street and Out Risbygate.
The practice has been seen across Britian for decades, with a common held belief that the presence of shoes indicates drug dealing territories or that drugs are available nearby.
Others believe the behaviour is purely trivial and is done as a prank.
Suffolk police said it is aware of the incidents and that steps are being made with partners to remove the footwear.
The force added that it does not believe the shoes are "indicative of drug dealing or other criminality".

Speaking previously, Matt Paisley, locality inspector for Bury St Edmunds, said: "We are aware of the presence of shoes and trainers appearing over power lines in and around Bury St Edmunds.
"Enquiries have been carried out and there is nothing currently to suggest that the presence is indicative of any drug dealing or other criminality.
"We are working with our partners to ensure these items are removed from public visibility in a timely manner.
