Mumbai, June 14 (IANS) The Mumbai police chief denied Tuesday any links between the transfer of a senior officer and the cold-blooded killing of a senior journalist who specialized on the underworld.

 
 Assistant Commissioner of Police Anil Mahabole "is not at all involved in this attack", Mumbai Police Commissioner Aroop Patnaik said as journalists angry over the Saturday murder stepped up pressure to net the killers.
 
 Mahabole also told Times Now that he had no idea why he has been transferred out of the Azad Maidan division of south Mumbai while police sources tried to establish a link of Mahabole's transfer with Dey's murder.
 
 Mahabole insisted that he had no problems with Dey, an ace investigative reporter who was killed by four motorcycle-borne assailants near his residence Saturday afternoon.
 
 Mahabole has several pending inquiries against him. T.K. Dwivedi, a colleague of Dey, accused Mahabole of threatening him. The officer denied the charge.
 
 "A few weeks ago, when I was arrested in connection with an Official Secrets Acts case, Mahabole threatened me inside the Government Railway Police lock-up. I lodged a complaint," Dwivedi, who goes by the alias 'Akela', told IANS Tuesday.
 
 Mahabole, in turn, said it was Dwivedi who had problems with him and that he (Mahabole) had sought permission from his seniors to file a defamation case against the journalist.
 
 Mumbai Police Monday released a sketch of one of the four suspected killers of Dey.
 
 The sketch, prepared following inputs of witnesses, described the suspect as a young man of 20-25 years, dark complexioned, about 5 feet 5 inches tall and of medium build.
 
 More than 500 journalists of print and electronic media Monday took out a protest march to the state secretariat.
 
 The journalists met Maharashtra Chief Minister Prithviraj Chavan, who rejected their demand for the Central Bureau of Investigation (CBI) probe into Dey's killing.
 
 Unhappy with the pace of investigations, the journalists plan to launch a relay hunger strike and move the Bombay High Court. They want a direction to the government to hand over the murder probe to the CBI.
