Kuldeep Singh, the only eyewitness to the Lucknow passport controversy, has told India Today that he was kidnapped at gunpoint and later sedated.

He said he somehow managed to escape and informed the police about the entire incident. A written complaint has been filed with the police and the matter is being investigated.

Kuldeep Singh is an eyewitness in the passport ordeal of the inter-faith couple. He had defended passport officer Vikas Mishra over the entire controversy.

According to him, he was kidnapped on Saturday afternoon by three people in a car at gunpoint. After sometime he fainted after being sedated by the kidnappers.

"When I regained consciousness I saw the kidnappers having tea at a shop somewhere. Somehow I managed to flee from the car and went straight to a nearby police post with the help of locals. Later on I found out I was in Lakhimpur Kheri district," Kuldeep told India Today.

He said he was not sure whether his kidnapping was related to the passport issue or not.

"Without evidence I cannot say my kidnapping was linked to the passport controversy. Lakhimpur Kheri police brought me to Lucknow after recording my statement. I am getting a case filed at Jankiupuram police station. I have no enmity with anyone. Cops must investigate the case and find out the culprits," added Kuldeep.

Kuldeep also reiterated that the passport officer Vikas Mishra did nothing wrong and was unnecessarily transferred.

"I was there when the incident happened. Vikas Mishra didn't misbehave with the couple. The government has taken action against him without proper investigation. It is very unfair," said Kuldeep.

SSP Lucknow Deepak Kumar said the investigation was being conducted by the police. We have taken the complaint and necessary action will be taken, he said.

Meanwhile a police team will go to the inter-faith couple's home on Monday to verify their address and other details required for passport verification.

BJP and Shiv Sena leaders have also demanded a proper enquiry into the passport controversy.
