A 23-YEAR-OLD man was jailed for seven months on Friday for using a brick to hit another on the head.

Kenny Lee Jialong, then a full-time national serviceman, admitted hitting Mr Heyden Tan on the head with the brick along Mosque Street on Aug 26, 2006.

The 26-year-old victim and his brother had gone to a pub there at about 11pm on Aug 25 to meet their friends. Lee and his friends were also at the Whitehouse Pub.

Sometime past 3am while Mr Tan was outside, Lee suddenly came from behind and attacked the victim with the brick, said Assistant Public Prosecutor Christine Liu.

Mr Tan lost consciousness and fell to the ground. Lee dragged him to a distance away and started kicking him with a few other unknown men.

Mr Tan's brother and friend later rushed to help but the latter was attacked as well.

The assault eventually subsided when some other patrons came to help.

Lee, who has previous convictions for theft, was awaiting to be sentenced for rioting then.

He could have been jailed for up to one year and/or fined up to $1,000 for voluntarily causing hurt.
