FRANKFURT (Reuters) - Deutsche Bank bounced back to profit in the third quarter, as it released reserves set aside for investor lawsuits over its Postbank division and as its global investment bank fired on all cylinders.

The bank's net profit attributable to shareholders was 1.461 billion euros ($1.58 billion) in the quarter, figures showed on Wednesday. That compares with a profit of 1.031 billion euros a year earlier and a loss of 143 million euros in the second quarter.

It is slightly better than analyst expectations for a profit of around 1.4 billion euros.
