A computer expert claimed today it was highly unlikely extremist Islamic propaganda was planted on a terror suspect's laptop.

Mohammed Atif Siddique's laptop was seized at Glasgow Airport on April 5 last year, as he was about to fly out to Pakistan.

The High Court in Glasgow has heard footage found on it showed Osama Bin Laden calling for holy war, the Twin Towers exploding and other clips urging young Muslims to become suicide bombers.

The laptop was switched on by a Special Branch cop against guidelines and left on for 71 minutes.

Brian McConnachie QC, prosecuting, asked IT specialist Michael Dickson: "Would it be realistic someone could have placed that material in 71 minutes?"

Mr Dickson replied: "It would be possible to transfer the material, however, it would take effort to make it look like it had come across at different times."

Mr McConnachie then asked: "Would it be possible to do this in such a time without training?"

He replied: "No, I would definitely not say so."

Mr Dickson claimed special software would be needed together with computer expertise.

Earlier Mr Dickson said someone using the account of M Atif Siddique viewed a fundamentalist Islam website featuring Abu Hamza at Ibrox public library and other Islamic websites on four dates in February and March last year.

Siddique, of Alva, Clackmannanshire, denies all charges against him.

The five charges against Siddique include allegations he threatened to become a suicide bomber and carry out terrorism, and provided instruction on using or making firearms and explosives on his three websites.

The trial, before Lord Carloway, continues.
