A high-profile drug liability trial was delayed briefly Wednesday when a device believed to be used in bomb detection training was discovered in the Atlantic City, N.J., courthouse, authorities said.

Authorities evacuated the Atlantic County Civil Courthouse, where two men’s case against Merck & Co. over its withdrawn painkiller Vioxx is in its third week, at about 8:06 a.m. after a sheriff’s deputy discovered it in the drawer of a first-floor office, said Atlantic County Undersheriff John Tuohy.
