Anglesey manhole cover theft and sign vandalism warning
Vandals damaging road signs could be putting motorists' lives at risk on Anglesey, officials have warned.
Meanwhile, North Wales Police are appealing for information after a spate of thefts of manhole covers and scrap metal from roadsides on the island.
The county council says vandals have damaged three electronic road safety signs in separate attacks.
Cabling was ripped from a sign in Menai Bridge and signs in Valley and Rhosybol were broken when turned the wrong way.
Anglesey council roads officer Terfel Jones said: "These are special flashing speed signs which have been installed at the request of local communities because of concerns about speeding motorists and road safety.
"The signs help make drivers aware of their speed and contribute towards making local communities safer."
He said they had been repaired at considerable expense.
"However, in view of the current financial difficulties, the authority won't be able to repair or replace any more which means that they will have to be removed and this could ultimately put lives at risk."
Police said they also wanted to speak to anyone tampering with items at the side of roads after the disappearance of manhole covers.
Insp Gareth Evans of North Wales Police said: "We have had a number of incidents so I am asking members of the public to contact us if they see any persons who they feel may not be official workers".
