Another 5G phone mast has been set on fire on Merseyside.
Police and fire services were called to the mobile phone telecoms mast in Rathmore Avenue, Mossley Hill, south Liverpool, shortly before midnight on Tuesday.
A man in dark clothing had been seen at the base of the mast shortly before the blaze started and left the area on an electric bike, Merseyside Police said.
Officers attended along with Merseyside Fire and Rescue Service and an investigation been launched.
Detective Sergeant Richie Shillito, of Merseyside Police, said: "These are challenging times for everyone, and members of the public are more dependent than ever on technology such as mobile phones to keep in touch with their friends and family.
"For many vulnerable people isolating and shielding, it is their only means of contact with the outside world.
"People may also need to use their phone to contact the emergency services, and extremely reckless acts like this could leave them with no signal and put someone's life at risk."
Earlier this month, Michael Whitty was warned by a judge that he faces a prison sentence after admitting he set a telephone mast on fire in Kirkby, Merseyside, on April 15.
A number of attacks on phone masts across the country are believed to be linked to false claims that the 5G network is spreading coronavirus via electro-magnetic radiation.
