“You don’t say bad things about someone’s mother, especially when you don’t really know each other that well,” the boy told police, according to local paper Göteborgsposten (GP).
The two 17-year-olds were working together at a Gothenburg telemarketing company in December last year when the incident occurred.
While the staff was having a laugh and there were general high jinks in the office, one of the 17-year-old boys held up his mobile phone and showing a picture of a naked girl he said:
“Your mum sent me a picture.”
His targeted co-worker reacted immediately.
Picking up one of the office chairs, a heavy desk chair with wheels, he raised it over his head and subsequently flung the seat at the boy with the offending image, according to the paper.
On impact the boy with the phone started to bleed profusely and had to be taken to hospital.
The chair-throwing teen has now been charged with assault, but denies the charge. In police interrogation, at which his mother was present, he defended himself.
“Everything went black before my eyes when he showed me the picture and I felt sad and humiliated. My mother means everything to me,” said the boy according to GP.
