Thai police say the deadly fall from a luxury hotel room of a British executive at India's automotive giant Tata Motors may have been a suicide.

Managing Director Karl Slym died Sunday while in Bangkok to attend a board meeting of the company's Thai affiliate.

Maj. Gen. Pornchai Sutheerakhun, head of the Thai police forensic unit, said Monday that Slym died from a broken skull and injuries to his brain and other internal organs after falling from his 22nd floor room.

Police Lt. Somyot Bunnakaew said investigators' initial assumption is that Slym killed himself because of a suicide note left in the hotel room referring to domestic problems. He said the letter was being analyzed to confirm it was written by Slym.
