A man who said he murdered a Glasgow shopkeeper because of his version of Islamic beliefs has released messages from prison calling on his supporters to kill other "insulters", say reports on Friday (23 September).

Tanveer Ahmed, 32, stabbed to death Asad Shah because he felt the shopkeeper, who followed the Ahmadiyya brand of Islam, was guilty of "disrespecting the prophet Mohamed". The Ahmadiyya are accused of not believing Mohammed to be the final Prophet, which many Muslims regard as blasphemous.

Despite his 27-year prison sentence, it has emerged that Ahmed has released a speech on YouTube in Urdu, calling Ahmadi Muslims "frauds" for their beliefs.

He said that he sent Shah "to hell with the help of Allah, the prophet, angels and saints.

"Whoever and wherever is listening my voice must make a resolve to protect the finality of prophethood," he says.

"We will save the Lord's followers from going down to the hell – will protect their faith," the Independent reported.

In one of five messages uploaded to the same YouTube account - apparently via a mobile phone - Ahmed said: "There's only one punishment for those who insult the prohphet: Cut off their heads, cut off their heads, cut off their heads."

Police Scotland have launched an investigation into the audio messages, which could constitute hate speech or incitement.

Margaret Ferrier, the Scottish National Party MP for Rutherglenand Hamilton West,has written to the Scottish Prison Service to demand convicts are not able to broadcast "extremist rhetoric".

She told the Independent: "It is worrying that the persecution of the Ahmadi Muslim community face in Pakistan appears to now be manifesting itself in the UK.

"The brutal murder of Asad Shah is the only reminder needed that this issue needs to be treated with the utmost seriousness."

Ahmed will serve a minimum of 27 years in prison for the murder. Sentencing Ahmed at the High Court in Glasgow, judge Lady Rae said he was responsible for the "barbaric killing of a peace-loving man" and "an appalling display of merciless violence".
