Jaipur, Aug 31 (IANS): Over a dozen police teams were constituted to search for Indian Administrative Service (IAS) officer Naveen Jain, who went missing from a restaurant in Rajasthan's Alwar district a day earlier, police said Wednesday.

Jain, 36, who was posted as commissioner in the state's settlement department in Jaipur, left behind a note for his wife and son saying they should take care of themselves.

"Around a dozen teams have been constituted to search for him and rushed to various places throughout the country," a police office told IANS.

"His wife Sunita alerted us within less than 30 minutes after she found the note. But as the restaurant is situated on the national highway between Jaipur and Delhi, he could have easily got some transport," said the officer.

Chief minister Ashok Gehlot also sought details of the incident from the police.

Jain's wife Sunita and son Gautam returned to Jaipur Tuesday evening.

According to police, Jain had gone to a restaurant in Shahajanpur, some 150 km from here, along with his wife and son for breakfast.

"While they were having food, Jain got up from the table on the pretext of making a call and walked out," said Additional Superintendent of Police Sangram Singh.

Jain then left a note in their car parked outside.

"In the note, he repented that he had not been able to provide a house to his family. He said that he was going somewhere and should not be disturbed," said the officer.

The entire state police machinery was jolted into action following the officer's disappearance. Teams have been rushed to Haryana and Delhi and exit routes of the state are being checked.

Sources said Jain had been transferred to Jaipur in the first week of August from Baran, where he was posted as district collector. After his transfer, there was a controversy over the allotment of an official residence to him.

Jain, who belongs to Haryana, had also been district collector in Hanumangarh, Karauli and Rajsamand districts of Rajasthan.
