The suspect, Sarju Markam, 33, was arrested Monday at his job where he works as a car mechanic. Markam, who is married with children, was upset after the bride rejected his desire to have her as his second wife, police said. 

He was reportedly upset by her marriage. At one point, he called Hemendra and threatened him, police said. 

“They had an altercation. Hemendra also had a talk with his fiancé and the issue was settled,” Superintendent of Police Lal Umed Singh told The Express. 

Authorities suspect Markam allegedly used ammonium nitrate he stole from a previous job in 2015 to make the explosive device. He also allegedly used gasoline and several other materials. 

He allegedly had a friend drive him to the wedding venue where he placed the bomb under several gifts and left. Markam faces life in prison.
