M'sian police: Blast 'linked to an underworld tussle'
As Malaysian police investigate the motive of the incident, there has been speculation that it could be linked to a gangland fight or business feud, among other things.
Kuala Lumpur Criminal Investigation Department chief Senior Assistant Commissioner Gan Kong Meng said: "We believe this is linked to an underworld tussle."
Deputy Home Minister Wan Junaidi Tuanku Jaafar said it could have been done by locals or immigrants.
He said: "It could also have been due to business rivalry between the clubs in the area."
Prime Minister Najib Razak has vowed that the authorities would track down and punish the people behind the explosion, reported The Star.
"I condemn in the strongest terms the violence that occurred this morning in Bukit Bintang.
"Such lawlessness will not be tolerated. Police investigations are underway and the perpetrators of this crime will be found and brought to justice," said Mr Najib.
