"From an early stage with this team he was subjected to acts of bullying that went beyond anything that could be described as banter or hi-jinx in the workplace.

"The first incident happened when they were working in London.

"On one night during the week the group would tend to go out socialising and drinking - that night was usually Thursday night.

"On this occasion [the teenager] did not accompany his colleagues and he went to bed.

"He was woken by Rose who was above him with a deodorant can in one hand and a cigarette lighter in another.

"He discharged the spray that narrowly missed [the teenager's] head because he had the presence of mind to pull the duvet over his head.

"Afterwards Joseph Rose was seen stamping out the smoke from the duvet."

Mr Newman said while Rose was attacking the teenager with the lighter and deodorant Addison was sat in the room taking pictures on his mobile phone.

The prosecutor said the second incident took place a month later in August 2014, when the team was in Basildon, Essex.
