Feb 26 (Reuters) - India's federal investigating agency said on Thursday it has opened a second criminal case against industrialist Anil Ambani and his company Reliance Communications following a complaint from Bank of Baroda over alleged diversion of loans exceeding 22.20 billion rupees ($244.21 million).

The Central Bureau of Investigation said various documents related to the loan transactions have been recovered as part of its searches at Ambani's house and the company's offices.

The account books of Reliance Communications "were manipulated and irregularities concealed", the agency said.

A spokesperson for Anil Ambani, Reliance Group and Bank of Baroda did not immediately respond to Reuters requests for comment.

Last year, the agency opened its first criminal case against Ambani and the company based on a complaint from India's largest bank, State Bank of India, over alleged fraud.
