Berlin  - The Chief Executive of Deutsche Bank, Josef Ackermann, has recovered following a dizzy spell, a spokesman for the bank announced Thursday.

"I can confirm that he went to hospital for a brief medical check," spokesman Ronald Weichert said, adding that Ackermann was now back at work.

At a reception Wednesday evening in Berlin, the 60-year-old briefly felt unwell, possibly as a result of food he had eaten. An ambulance took him to hospital at around 9 pm, according to Berlin's emergency services.

Ackermann returned to his hotel room later that night.

Deutsche Bank shares plunged Wednesday, following the announcement of an anticipated 3.9-billion-euro (5.1-billion-dollar) loss for 2008. (dpa)
