Jailed: Danh Van Le has been sentenced to nine months in prison for a bomb hoax

A YouTube cameraman has been jailed for filming pranks which involved planting bomb hoaxes and carrying out fake robberies at London tourist destinations.

Danh Van Le, 31, teamed up with a teenage boy for the stunts which he later shared on an online video channel called 'Trollstation'.

He was jailed for nine months yesterday after admitting a string of public order offences at Inner London Crown Court.

The videos showed the 15-year-old boy approaching strangers and revealing a clock inside a briefcase.

He then dumped the bag and ran off, scaring bystanders into thinking that there could be a bomb inside.

The clock stunt was filmed in September as an homage to US teenager Ahmed Mohamed, who was arrested after his home-made clock was mistaken for a bomb.

Van Le also filmed two hoaxes at the Tate and the National Portrait Gallery, where fake robbers tights over their faces ran into the galleries holding paintings to trick others into thinking it was a heist.

He admitted one count of bomb hoax placing with intent, involving eight incidents, and was sentenced to 24 weeks in jail.

The teenage boy - who cannot be named for legal reasons - admitted the same charge and was given a 12-month intense referral order.

Van Le also admitted using threatening, abusive or insulting words or behaviour with intent to cause fear or violence in connection with the gallery incidents, and was sentenced to a further 12 weeks.

A spokesman for Trollstation - which claims to be the biggest online prankster YouTube channel in the UK with 680,000 subscribers - said the sentences were 'pretty unfair'.

He added: 'A big production crew for a Jackie Chan movie blew up a bus in London in February and didn't warn anybody apart from some local people.

'In a way that impacted more people and scared a lot more people but a small production does this low budget thing and this is how it is dealt with.'

Van Le - known as 'DigiDan' - is one of the founding members of the London-based Trollstation team, who started posting their controversial videos on YouTube in November 2013.
