Student accidentally concocts deadly explosive used in 7/7 bombings in university lab

A university’s science department had to be evacuated after a student accidentally concocted a deadly explosive – the same as that used in the 7/7 bombings – in his university lab.

The explosive substance TATP, or acetone peroxide, was created in the University of Bristol’s chemistry lab, according to a staff member.

It is the same chemical that was used in the 7/7 bombings in London as well as terror attacks in Paris and Brussels.

Students from the School of Chemistry were evacuated after the dangerous mixture was discovered in a lab at 2.30pm on Friday.

Five fire engines as well as police and ambulances attended as a precaution and a bomb disposal team was dispatched to help dispose of the chemical.

A member of staff who was working in the building at the time of the evacuation said the TATP was created as a by-product of an experiment.

They added: ‘There are two levels and both floors were filled with first and second year students, and probably around 150 just in one lab alone.

‘As you can imagine, everyone didn’t stay calm and got out very quickly. I was told by those working closely to the lab it was TATP.’

TATP is a homemade explosive substance and has been used in improvised explosive devices (IED).

A spokesman for Bristol University did not confirm the nature of the substance but said the ‘unstable substance’ was made accidentally.

He added: ‘Our chemistry building and those buildings in the near vicinity were evacuated earlier this afternoon as a precaution, due to an unstable substance being manufactured by mistake.

‘The substance has been disposed of safely and no one was injured. We will be looking into what happened and seeing what lessons can be learned.’

Avon and Somerset Constabulary confirmed the incident was not being treated as suspicious.
