Authorities say no explosive device was found at a Long Island building that houses offices belonging to Cablevision Systems Corp.

A bomb threat led authorities to clear out the building off the Jericho Turnpike in Syosset on Sunday.

Nassau County police say they received a call from Cablevision about 6:30 p.m. They couldn’t immediately say how many people were in the building at the time of the threat.

Police are trying to determine who made a threatening call to the company.

Cablevision spokeswoman Kim Kerns says the company is cooperating with authorities. She says the company will have no further comment.
