Dhaka: A cricket umpire killed a teenage spectator in Bangladesh by hitting him on the head with a bat in a dispute over a contested decision, police said on Sunday.

Nazrul Islam, 15, ran onto the pitch during an amateur game in the remote northern district of Kishoreganj and started an argument with the umpire, who took one of the players' bats and hit the teenager.

Islam showed no serious injury from the blow during the game on Friday but suffered an internal hemorrhage overnight and died in hospital the following day, local police chief Mosharraf Hossain told AFP.

"The two argued over a not-out decision by the umpire. He accused the umpire of bias. At one stage, the umpire became angry, took a bat and hit the young boy on the head," Hossain said.

The umpire was being sought for questioning but had gone into hiding, he added.

Cricket is a hugely popular sport in Bangladesh, which last year co-hosted the World Cup with India and Sri Lanka.
