UK's SFO initiates investigation into Tata Steel's operations: Report

New Delhi: UK`s Serious Fraud Office has initiated a criminal investigation into Tata Steel`s operations, the Telegraph reported on Thursday.

Police officers are investigating charges that Tata Steel`s staff in and around its Yorkshire`s site, may have faked certificates on the composition of the products before its sale, the newspaper said.

Examined documents have affected 500 customers, including BAE and Rolls-Royce , Telegraph said.

Tata , the biggest steel producer in Britain, has put its British businesses up for sale due to high costs, weak demand and a flood of cheap supplies from top producer China.

The British government, under fire for the way it has responded to the crisis, opened talks with potential buyers for Tata Steel`s UK operations, including Gupta`s Liberty House, earlier this week.
