Darren Cornelius, 35, was found to have the knife and the mobile device hidden in his cell during a routine search at HMP Edinburgh on October 7 last year.

Cornelius did appear in the dock on Tuesday where he was handed an 80 day custodial jail term by Sheriff John Cook that will run consecutively to his current sentence.
Cornelius was first caged aged just 11 when he was sent to a young offenders institution for stabbing a nine-year-old schoolgirl in Edinburgh in 2000. He abducted the girl from her grandmother’s house before stabbing her eight times - narrowly missing the artery in her throat - and then left her for dead near the city’s Fountain Park leisure complex.
He avoided an attempted murder conviction due to his low mental age but was ordered to spend 17 months in secure accommodation.

Pacitti was convicted in August 2007 at the High Court in Glasgow of murdering George Walker, who had a role in the Ken Loach directed movie Sweet Sixteen. Pacitti shot Mr Walker as he sat in his home in August 2006. He was with his father, also called George, who was believed to have been the intended target of the killing.
Cornelius was subsequently sentenced to a further 16 months for a blade attack on two prison warders at HMP Shotts, Lanarkshire, in 2022.
