Feb 13 (Reuters) - U.S.-based investment firm Carlyle

Group ( CG ) has entered India's auto components market by

buying a controlling stake in an entity formed by the

combination of Indian auto parts companies Highway Industries

and Roop Automotives.

Equity for the investment will come from funds affiliated

with Carlyle Asia Partners, the firm said on Wednesday without

disclosing any financial details.

Highway Industries is a manufacturer of powertrain parts and

subsystems. Roop Automotives produces steering yokes and exports

them to Europe and North America.

The founders of both the Indian firms will continue to hold

stakes in the merged platform, Carlyle said.

The size of the deal is about $400 million, where Carlyle

will own 65%-70% stake in the platform, the Economic Times

reported citing sources.

On January 7, India's competition regulator gave its nod to

a transaction that constituted a securities swap between Highway

and Roop, and a 68.9% stake buy in Roop by Carlyle.
