Another Indian minister is under investigation for his alleged role in the corruption scandal involving India's telecommunications industry.

The Central Bureau of Investigation says it is probing the role of the country's current textiles minister, Dayanidhi Maran, in the scandal which is said to have cost the government up to $40 billion.

The CBI says it plans to question Maran on the allocation of mobile phone licenses during his time as telecom minister between 2004 and 2007.

More than a dozen other suspects, including another former telecom minister, A. Raja, are accused of conspiring to sell mobile phone licenses at cut-rate prices to the benefit of a few companies. Authorities jailed Raja after he resigned from his post last year.

Maran is a member of the DMK party, which is closely aligned with India's ruling Congress Party.

Indian Prime Minister Manmohan Singh's government has also been dealing with a corruption scandal involving last year's Commonwealth Games in New Delhi.
