"The Editors Guild deplores the law enforcement agencies' inability to protect the life of a journalist engaged in carrying out his professional duties at great risk to himself," Guild president T N Ninan and Secretary Coomi Kapoor said in a statement here.
They said initial reports suggest that the crime mafia may have been behind the killing.
Remembering Dey as a "courageous reporter" who undertook to expose the underworld, they said, "as editor of the special investigation team of the Midday newspaper and earlier with Indian Express newspaper, he had relentlessly exposed Mumbai's criminal mafia despite numerous threats to his life."
"The Guild demands that the state authorities speedily bring Dey's killers to justice," Ninan and Kapoor said.
