Gold and jewellery establishments in the national capital remained closed for the 13th day on Wednesday after the Income Tax Department conducted surveys following reports of alleged profiteering and tax evasion by traders through demonetised notes.

The survey operations were carried out on November 10 in at least four locations in Delhi-NCR region, including Dariba Kalan, Chandni Chowk and Karol Bagh.

The government on November 8 announced the demonetisation of 500 and 1,000 rupee notes to flush out black money.

Most of the jewellery houses in the national capital have been closed since November 11.

According to sources, officials of Directorate General of Central Excise Intelligence (DGCEI), an arm under the Finance Ministry, sent notices to these jewellers seeking details of the gold sales.
