Ahead of Independence Day, an added security concern was keeping Delhi Police on its toes -- a Pakistani national missing from his central Delhi hotel room for the past fortnight.

Mohammad Salim, who came to Delhi on a tourist visa on July 22, has been missing from his hotel room in central Delhi's Nabi Karim area since July 26 -- and police have made little headway in the case.

Deputy Commissioner of Police (Central) Parmaditya told IANS on Monday: "A missing complaint was filed on July 26 and we are looking for the missing tourist."

Salim went missing from the hotel room with all his baggage, the police officer said. 

According to a senior police officer, the police is also looking for the persons with whom Salim was in touch after coming to Delhi.

The officer said that several teams have been formed to trace the Pakistani national.
