US national Kenneth Haywood, who left India last month while being investigated in connection with the Ahmedabad bomb blasts e-mail sent from his account, is set to return to Mumbai tonight in a bid to clear his name.

Sources said Haywood, the Navi Mumbai-based employee of business skills coaching firm Campbell White, is flying back from his home in the US through London on British Airways flight BA 139 due to land after midnight on Wednesday.

Sources said Haywood sent “feelers” to Mumbai Police that he regretted the way he left India despite a look-out notice. While he is not expected to be arrested since the Maharashtra Anti-Terrorism Squad (ATS) has since given him a clean chit, Haywood is expected to visit ATS tomorrow.

Haywood and nine others who had access to the network — from where the email was sent allegedly by a group called the Indian Mujahideen — were subjected to polygraph and brain-mapping tests on August 13. Although there were no restrictions on his movement and his passport wasn’t seized, Haywood had been asked to stay put in the country and a lookout notice was circulated. But he left with his wife and daughters on August 17. A Home Ministry probe blamed his exit on a human error by the Immigration Department at Delhi’s Indira Gandhi International Airport.
