Initial investigation into the death of Tata Motors' managing director Karl Slym has suggested that the executive might have committed suicide, Bangkok police said.

Slym, 51, died in Bangkok after a fall from the 22nd floor of the Shangri-La hotel in the capital of Thailand on Sunday. Prior to his death, he had attended a board meeting of Tata Motors' Thailand unit in the capital. He was staying with his wife in the hotel. His dead body was found on the fourth floor that juts out above lower floors of the hotel.

Police Lieutenant Somyot Boonyakaew, who is leading the investigation team, said the investigators found no signs of a struggle and that the window was so small that it wasn't possible that he would have slipped.

Speaking on the topic, Boonyakaew said, "We didn't find any sign of a struggle. The window was very small so it was not possible that he would have slipped. From my initial investigation we believe he jumped."

The police also found a note, written in English, which is being translated into Thai. Police believe that the note may shed more light on the cause of the executive's death. Meanwhile, doctors are conducting an autopsy on the dead executive's body.

Slym had joined Tata Motors in October 2012, as part of a major management overhaul. He was playing a key role in the company's strategy to regain the market share it lost to its rivals in the domestic market. His untimely death might prove to be a speed breaker in that process.
