The publisher of popular gangster comic Teddy Boy says the torture and killing of Luk Chi-wai were not inspired by the weekly.
The comic book was cited in court as being read by the young defendants.
Paul Chu Shun-po, administrative manager of King's Foundation, which publishes Teddy Boy, said there was no evidence the group had copied acts of violence from the comic book.
Mr Chu said the comics described the reality of the 'fighting world' rather than glorifying triad members.
'I don't see the books doing harm to young people,' he said.
Publications can be classified as not suitable for children under the Obscene Articles Ordinance. But none of last year's issues of Teddy Boy were ordered to be wrapped in a plastic bag with a warning that sales were restricted to adult readers.
