The Central Bureau of Investigation (CBI) is carrying out raids at the residences of former Union minister P Chidambaram and his son Karti Chidambaram in Chennai.

According to sources, the raids began early morning.

More details are awaited.

In April this year, the Enforcement Directorate (ED) had issued a show-cause notice to Karti Chidambaram and a firm purportedly linked to him for alleged violations of the FEMA laws to the tune of Rs 45 crore.

The agency also issued a similar notice, after over two years of investigations, to another firm M/s Vasan Health Care Private Limited, which is based in Chennai, for alleged forex violations of Rs 2,262 crore.
