Streets are clear after a bomb threat targeted Greenbridge Development around 7 a.m. Thursday.
The caller said the bomb was in the Greenbridge development at 400 W. Rosemary St. Police performed a sweep of the building and did not find one.
The call came to 911 from an untrackable phone, Chapel Hill police Lt. Kevin Gunter said. Police evacuated the building and closed traffic in surrounding downtown streets, which re-opened at 9 a.m.
The seven and 10-story Greenbridge buildings have been targeted before -- once with a bomb threat this summer and again with $11,000 in graffiti last month.
Critics of Greenbridge say the development has caused gentrification with its presence in the historically black and low-income Northside neighborhood.
Gunter said police don't know yet whether the incidents are related.
Greenbridge spokesman Mark Velve said it was business as usual in the showroom today.
