(CNN) -- In a brazen daylight attack Saturday in the Indian city of Mumbai, gunmen shot and killed a veteran journalist who reported on the city's underworld.
Jyotirmoy Dey, was rushed to a hospital where he died of five gunshot wounds, reported CNN's sister network, CNN-IBN.It quoted police as saying that four men on two motorbikes pulled up to Dey, who was also riding a bike, and shot him from behind at close range.
Police are searching for the gunmen, who were able to escape the scene.
Dey had covered crime for two decades and was most recently writing for an English language tabloid called Mid Day.
The newspaper posted a statement on its website that called Dey "one of the pillars" of its newsroom.
It would not comment on the circumstances of Dey's killing but speculation surfaced that it was act committed by someone who intended to silence him.
"We will not stop doing investigating stories, and we will not bow to criminals," the newspaper said.
Editor Sachin Kalbag told CNN-IBN that he was not aware of any threats made against Dey.
"Everything was normal when I last met him, which was yesterday," Kalbag said. "This is an attack not on a journalist, but on the media fraternity."
Dey penned numerous articles on Mumbai's mafia and published two books on crime -- "Zero Dial: The Dangerous World of Informers" and "Khallas," which was about Mumbai's organized crime scene.
"I don't know why he was shot dead. Maybe some reporting of his had hurt some mafia," Chhagan Bhujbal, the Maharashtra state minister for public works, told CNN-IBN. "We have a lost an important reporter in the state."
"Dey was a very honest person," Bhujbal said. "He used to write on the underworld. He was not targeting anyone in particular."
