Bangkok, Jan 27 (IANS): Thai Police Monday ruled out murder as the cause for the death of Tata Motors managing director Karl Slym, who fell from the 22nd floor of a Bangkok hotel Sunday.

"We can rule out murder in this case. We are still investigating his death," the Bangkok Post quoted Somyot Boonyakeow, a police official, as saying.

Slym, 51, died Sunday after he fell from the Shangri-la hotel in the city's Yannawa district.

Police said they found a three-page handwritten note in his room. The note, written in English, is being translated into Thai.

There was no sign of struggle inside his room, police said.

He checked into the hotel with his wife Jan 24.

A British national, Slym was in the capital to attend a board meeting of Tata's subsidiary in Thailand.

Slym joined Tata Motors in 2012 to revive its declining sales and market share in India.

He was responsible for charting the company's strategy to regain momentum in the market.

Slym was the executive vice-president at SGMW Motors, China, a General Motors joint venture, before joining Tata Motors.

Between 2007 and 2011, he steered GM India through very tough times.
