AKRON, Ohio (AP) __ A federal judge overseeing the case against a group of men charged with plotting to bomb a highway bridge in Ohio won't allow prosecutors to use a recording of what they say is a confession.

U.S. District Court Judge David Dowd in Akron ruled Monday that he won't allow the partial audio tape to be played at the trial but will allow the agent who conducted the interview to testify.

The Plain Dealer in Cleveland reports that the defense attorney for 26-year-old Douglas L. Wright of Indianapolis argued that the FBI didn't record the entire interview.

Five men were arrested in late April when they allegedly tried to detonate what turned out to be a dud bomb provided by an FBI undercover informant.

One of them pleaded guilty in July.
