The accused person in connection with the mysterious death of renowned filmmaker Ritwik Ghatak’s granddaughter last month, who was arrested near Sonarpur in the State’s South 24 Parganas district on Tuesday, was remanded in police custody for seven days by a local court on Wednesday.

 “The sole accused Gyanjit Patar involved in Aditi Ghatak’s accident case has been arrested,” a senior police official said.

 Ms. Ghatak met with an accident on November 30, 2012 and succumbed to her injuries on December 2. After her death, the family had lodged a police complaint alleging that it was not an accident, but a murder.

 Ms. Ghatak had gone out with a few friends on November 30. Later in the evening she was dragged out from a car that had plunged into a canal in the Sonarpur area. The family had raised questions about how she was the only one to have sustained serious injuries while the others had escaped unhurt. Patar was one of the friends with whom she had stepped out.

 He went on the run after the police complaint was lodged.
