Lakhan Singh hanged himself in Vijay Nagar police station here. He had allegedly thrown acid on a married woman after she refused to marry him. He was arrested late Friday night.
Superintendent of Police Shiv Shankar Yadav had called a press conference at 2.00 p.m. to announce Singh's arrest. Before he could address the media, he was informed about Lakhan Singh's suicide and rushed to the hospital, where the accused was declared dead.
Lakhan Singh had Friday thrown acid on Nisha Sheik, 30, who sustained 30 percent burn injuries on her face, torso and arms. She is in a stable condition in hospital. Lakhan Singh was an LPG cylinder supplier.
"The victim is from Madhepura in Bihar. She lives in Vijay Nagar area. The accused lived in the same locality," Yadav said.
