Broadband subscribers have been urged by a top police officer to ensure their broadband connections are fully secure.
The Scottish Crime and Drug Enforcement Agency's Detective Inspector Keith McDevitt has claimed that a failure to ensure wireless networks are protected could make it easy for people to make use of them.
He explained to the Daily Record that this means people could possibly find themselves embroiled in issues related to fraudulent activity, as criminals could use such connections to download indecent material or buy items with a stolen credit card.
Detective Inspector McDevitt told the newspaper: "The police may arrive at your home with a warrant to search, seize and examine your computers and for a period of time you are likely to be the suspect in a criminal investigation.
"And this is all because you failed to take some simple steps to secure your Wi-Fi connection."
According to broadband provider TalkTalk, around seven million homes are vulnerable to such Wi-Fi hijacking.
The company said the statistic was evidence as to why government plans to disconnect those suspected of illegal filesharing would not work.
