TAMPA, Fla. (AP) - A Tampa nursing home has been evacuated after a maintenance manager found a pipe bomb on his desk.

Police spokesman Laura McElroy said the bomb squad examined the suspicious package Wednesday morning and found three pipes strapped together. It's unclear why the nursing home was targeted. She said no threats have been made against Bayshore Pointe Nursing and Rehab Center.

McElroy said authorities have several strong leads and are pursuing possible suspects.

The roughly 50 evacuated residents should be able to return to the facility after the bomb team finishes a security sweep.
