Lucknow, Dec 16 (IANS) A hotel in Uttar Pradesh's Chandauli district is in trouble for providing a room to Bollywood star Aamir Khan without establishing his identity.

Police have served a notice to the owner of Saraswati Hotel, seeking an explanation for "flouting the basic rules for allotment of rooms in a hotel", a police officer said Wednesday.

For promoting his forthcoming movie "3 Idiots", Aamir Khan Saturday roamed around Varanasi district in the guise of an elderly Maulana.

He stayed in the Sarawsati hotel in adjoining Mugalsarai town, some 300 km from Lucknow.

"It's a security lapse. We want to know how the rooms were booked when the claimants did not reveal their true identity. Prior to allotting the rooms, the hotel staff must have checked their ID proof," Chandauli police chief Lakshmi Narayan told reporters.

"Prima facie, it is a clear case of not following procedural norms related to security measures. For this the license of the hotel could be cancelled," he added.

According to police, in the name of Akram Shah and Co, seven rooms were booked for Aamir and his team in the hotel. The actor arrived in Varanasi Friday and headed to other destination Sunday.
