A Heathrow worker who called herself the “Lyrical Terrorist” burst into tears today after becoming the first woman to be convicted under new terrorism legislation.

Samina Malik, 23, was found guilty at the Old Bailey of possessing records likely to be used for terrorism by a majority of 10 to one.

The court had heard that Malik, who worked at WH Smith, wrote poems entitled How To Behead and The Living Martyrs and stocked a "library" of documents useful to terrorists.

When her home was searched in October last year, police discovered a ring binder full of documents as well as a bracelet bearing the word "jihad". They also discovered a sticker on a mirror inside the door, bearing the words "lyrical terrorist".

In one handwritten document found by police, she wrote: "Many opportunities have been given to me but something always holds me back.

"I always sit alone to think and ponder how it would be to unite with the Muslim ummah and to go shoot rocket-launchers, help them load their ammunition, nurse the wounded, and what the atmosphere would be like."

Also found were publications by Sheikh Omar Bakri, the extremist cleric, as well as a printed-out version of the "declaration of war" by Osama bin Laden.

One poem found at her property, called The Living Martyrs, said: "Let us make Jihad/ Move to the front line/ To chop chop head of kuffar swine".

A second poem, called How to Behead, read: "It’s not as messy or as hard as some may think/ It’s all about the flow of the wrist."

Several documents were discovered on her computer, including The Mujaheddin Poisoner’s Handbook, Encyclopaedia Jihad, How To Win In Hand To Hand Combat, How To Make Bombs and Sniper Manual.

The court heard that Malik had also belonged to the social networking site Hi-5, a similar site to Facebook or MySpace. On this she listed her interests as: "Helping the mujahaddin in any way which I can ... I am well known as lyrical terrorist."

Under favourite TV shows, it said: "Watching videos by my Muslim brothers in Iraq, yep the beheading ones, watching video messages by Osama bin Laden and Ayman al-Zawahri and other videos which show massacres of the kaffirs."

In another internet entry, the court heard, she wrote the names Sheikh Abu Hamza al-Masri, Sheikh Abu Qatada, Sheikh Osama bin Laden and Abu Musa al Zarqawi.

Sentencing Malik for possessing records likely to be useful in terrorism under the Terrorism Act 2000, Judge Peter Beaumont, the Recorder of London, bailed her under what he described as "house arrest" to be sentenced on December 6 and ordered reports into her family background.

He told her: "You have been in many respects a complete enigma to me." He warned her that "all sentencing options remain open".
