New Delhi, Mar 11: The bus driver Ram Singh, who was the main accused in the infamous Delhi gangrape case, worked only with a single arm, but his body was found inside the cell of Tihar Jail No. 3 at a height of 9 feet,  with his neck tied with his shirt to a grill.

Questions arise how Ram Singh could reach such a height to commit suicide, sources say.

There were three other prisoners inside the cell alongwith Ram Singh, and they told jail officials that they were sleeping through the night.

The height of the cell is 12 feet, and the grill was at a height of 9 feet, to which Ram Singh's shirt was tied to.
