"In 2015, police arrested Sougat Mukherjee as a suspect in the case. The arrest was solely on the ground that the suspect had protruding teeth and Sougat Mukherjee had protruding teeth. Merely on that basis, they concluded that he is a possible suspect and they started the extradition proceedings against him," Jain said.
In 2015, the British authorities sent the letter of extradition to the government authorities in India, Jain said.
"Around April 2015, he was arrested by police on the request of the Interpol. He was released on bail immediately because we had challenged the procedure of the extradition and also, we had challenged on the ground that no formal request of extradition was made by the English authorities. Having said that, after the bail, he was required to cooperate in the investigation, he was required to visit police station every week," Jain added.
The lawyer said that Mukherjee was acquitted of all charges after "it was found that the murder was done by a Chinese man, who confessed the crime and was convicted."
Jain said the legal options are open for Mukherjee to seek compensation in this matter.
"Mukherjee was arrested on the basis of mistaken identity," the lawyer said.
