Sambia Sohrab has been charged with murder for hitting an air force personnel with his Audi car.

A Trinamool politician disowned by West Bengal's ruling party remains missing five days after his son allegedly ran over and killed an Air Force officer supervising Republic Day parade in Kolkata.The son, Sambia Sohrab, was arrested on Saturday in Kolkata. His friend, Shahnawaz Khan, who fled after the hit-and-run, was arrested in Delhi last night.But the father, Mohammad Sohrab is absconding, along with his older son Ambia. Police had issued a look out notice for all of them on 13 January, the day of the incident.Mohammed Sohrab has no links to the Trinamool, said party leader Sovan Chatterjee, who is also the Mayor of Kolkata. "Just because you and I are photographed together, it doesn't mean I am responsible if you create a problem or you are responsible if I create a problem," he told NDTV.A photograph of him and Mr Sohrab, wearing Trinamool shawls and campaigning in a jeep for Trinamool in last year's civic polls, was front page of The Telegraph today.Another picture shows Mr Sohrab and a Trinamool councillor who, sources say, was with the CPM, but brought into Trinamool by the missing politician.On 13 January, Sambia Sohrab was drinking till dawn with several friends at a place called Dahighat in Kolkata's Khidderpore area.Sambia's friends Shahnawaz and Jonny's families claim when the party ended, they left in a Skoda and Sambia alone in his Audi."Neither Jonny nor Shahnawaz were in the Audi when it hit the corporal," said Daanish Haq, a lawyer hired by Jonny's family.Defence spokesperson in Kolkata Wing Commander SS Birdi said eyewitnesses stated from day one only one person was in the Audi.But police want to interrogate Sambia's friends to crosscheck all their accounts."It was a reckless demon of a driver. Neither the driver nor his father is related to TMC. The law of the land will punish the culprit soon," said Trinamool leader Derek O'Brien on Saturday. He has described Mohamad Sohrab as a "minor Trinamool activist" and emphasised that he had been elected to the assembly in 2006 as a Rashtriya Janata Dal candidate, supported by the Left.But Mohammad Sohrab, big fruit merchant and builder in Kolkata's Burrabazar, apparently gravitated to Trinamool after the Left lost in Bengal. Trinamool sources say then General Secretary Mukul Roy roped in him in.Mr Roy was not available for comment.On the day of the incident, some newspapers reported, Mr Sohrab called some police officers for advice. He was reportedly told to leave town with his sons.These reports could however not be independently and officially confirmed by NDTV.
