Haroon Syed also pleaded guilty today to planning to detonate explosives at Buckingham Palace.

A teenager from west London has been convicted of plotting to bomb Elton John‘s Hyde Park show last year that fell on the anniversary of 9/11.

According to Sky, Haroon Syed pleaded guilty to planning terrorist acts at the show and at London’s Buckingham Palace, having been snared agreeing to pay £150 for a nail bomb from a security service officer posing as an extremist.

London’s Old Bailey heard Syed was “researching, planning and attempting to source” materials for homemade explosive devices for use in the UK, having searched the internet for busy UK locations and events to attack.

Syed had previously searched the internet for Isis and also told police that the password for his phone was “Isis.” He was caught online last year by British Security Service officers who posed as an extremist and discussed sourcing weapons in their online chats.

The 19-year-old was described by his defence team as “highly vulnerable due to family history, lack of education, addiction to violent online games and the arrest and imprisonment of his brother”.

Last June, Syed’s brother Nadir received a life sentence, with a minimum term of 15 years, after he was found guilty of plotting to carry out a beheading around Remembrance Sunday in 2014.

Judge Michael Topolski QC has adjourned sentencing until June 8 when a probation and psychiatric report can be carried out.
