ABC News has confirmed that the Secret Service arrested a sound engineer covering President Barack Obama's Iowa trip after marijuana was found in his backpack, Tuesday.

TVNewser has reported on the Web site mediabistro. com that the audio engineer, whose name was not reported, was part of ABC's crew covering the presidential visit. He was brought into the assignment by a local cameraman hired by ABC.

The report also said that the pot was discovered as the sound man and the cameraman were going through the routine Secret Service security sweep. Federal agents turned him over to local authorities.

ABC News spokesman Jeffrey Schneider told TVNewser, "While we did not hire this soundman directly, we certainly regret that the Secret Service and local authorities had to waste their valuable time dealing with this matter." (With Inputs from Agencies)
