Cops suspect that Dey's May visit to London was to meet the underworld fugitive don, Dawood Ibrahim, though it has been believed their meeting never took place. Instead, they say, Dey might have met some other member of the underworld. The police are now trying to ascertain this mystery man's identity.
A team has been already sent to Nainital to nab the two individuals (the key person suspected to be Babloo Srivastava) who allegedly supplied the murder weapon to the seven accused.
"The entire focus of the investigation is on Dey's London visit," a police officer told. It is also being believed that Chhota Rajan ordered to murder Dey as he was under the misconception that the scribe met Mirchi in London and passed on important information about Rajan or Rajan's location.
"We believe there is some relevance to this foreign trip. It was the first time Dey had travelled to the UK. And the fact that he went alone on a package tour does seem a little odd, particularly because it was not an official trip," said joint police commissioner (crime) Himanshu Roy.
"The police interrogated him before but the questioning was very broad that time. We will have a focused approach now," said Roy.
According to the cops, Rajan spoke to Dey five or six times in the days before the murder. In fact, it is also suspected that the two might have had heated up arguments. Now, the spotlight is fixed on Rajan, who has currently gone missing from the city.
