NEW YORK (AP) _ Deloitte Touche Tomhatsu is calling off talks regarding a possible acquisition of Arthur Andersen LLP, a big five accounting firm that has drawn scrutiny because of its role in the collapse of Enron.

In a statement Wednesday, New York-based Deloitte said it didn't want to ``pursue a business combination with Andersen Worldwide.

Deloitte spokesman Matthew Batters said talks between the two companies ended Wednesday.

The company said talks were ``unable to continue to the next stage because of discussions due to Andersen's unresolved litigation and legal issues.''

Experts have said that the biggest stumbling block to Andersen being sold would be related to avoiding Chicago-based Andersen's potential liability costs related to Enron's bankruptcy.
