Britain's Serious Fraud Office is investigating allegations of fraud, bribery and corruption in the civil aviation business of Airbus Group.

The European aircraft maker says in a statement released Sunday it has been informed of the investigation and will cooperate with the probe.

The fraud office also confirmed the investigation launched last month on allegations that relate to irregularities with third-party consultants.

Airbus revealed in April that it was speaking with British authorities over "inaccuracies" it had found in applications it had made for UK government credit guarantees. Airbus said at the time that the mistakes were uncovered in an internal review.

Airbus is headquartered in Toulouse, France, and has major U.K. operations near Bristol, and in north Wales.
