Lal Bahadur Singh (36) received an injury to his head 10 years ago. He allegedly believes that somebody has fitted a transmitter in his body and is doing something to him.

Today, he took a bus from his Sagarpur home in West Delhi and reached the Mughal Gardens around 11.15 am, roaming around for a bit afterwards.

“He was carrying some urea fertiliser in his pocket, which he consumed near gate number 35 of the gardens, which is on the side of the entry to Rashtrapati Bhavan. After consuming the urea, he informed a woman constable posted near the gate that he had eaten poison,” said an officer.

The constable informed the South Avenue police post and he was immediately rushed to RML hospital. “There was no vomiting. The urea did not affect his body much and he was normal in the next one hour,” said the officer.

His brothers, Ramlal and Mohar Singh, who work in a printing press in Samaipur Badli village, were informed. No suicide note was found on him. Singh belongs to Aurangabad in Bihar. He is married and has three children, who stay with his family in Bihar. He is metric pass.

Singh kept on repeating at the hospital: “Mere andar se ye machine nikalo (Remove this machine from my body).” Police officers said he was not mentally stable and could not even tell them his address in Sagarpur. “Since he is not mentally fit, we will not register any case against him. His family can take him home after he is discharged,” said an officer.

“He had come to Delhi 10 years ago with us and while working in a printing press, received an injury to his head with a hammer. About a year later, he started acting abnormally,” said Mohar Singh.

“Nobody wants to keep him in their house because he has some fight with his new landlords everyday and has also been unemployed for the last few months. We have not spoken to him properly in the last few months. He didn’t even go to Aurangabad two and a half months ago, when our mother passed away,” said Ramlal.
