Choudhary, who became a familiar name after his appearance in the popular reality show "Big Boss 2", is accused of "disruption of peace".
He came here from Delhi Thursday and was staying at a relative's house in Chitrakoot area.
"Raja claims that he had come to the Fortis Hospital in Jawahar Circle area around 2 a.m. Friday to see a patient admitted here. He was in a car and completely under the influence of alcohol," ACP Rajendra Singh told IANS.
Police said that as he was drunk therefore the security guards did not allow him to enter the hospital.
"There was a police control room vehicle stationed outside the hospital. When the policemen there tried to intervene, he started misbehaving with them also," said an officer.
Raja has been taken into custody and brought to the Jawahar Circle police station. He is booked under section 151 of the criminal procedure code (CrPC) for disruption of peace.
The officer said he will be presented in court Friday evening.
However, Raja told media persons that "when I reached the hospital, I was thronged by my fans who were seeking autographs. However, I tried to avoid them. This led to a minor scuffle".
