Law enforcement personnel are stationed outside of Phantom Fireworks offices in Youngstown on Belmont Avenue.

First reports of a police presence came in around 10:10 p.m. Tuesday night.

21 News called both Youngstown Fire and Police but neither could be reached.

The police presence comes just hours after President Donald Trump tweeted his appreciation to Phantom Fireworks CEO Bruce Zoldan for donating fireworks to Washington's 4th of July celebration.

Zoldan partnered with the Grucci family for a $750,000 donation to the firework display.

Bruce Zoldan provided this statement to 21 News about the incident:

"Unfortunately we had a bomb threat called in twice. Police and bomb squad and canine units came to search the entire premises. This was done shortly after President Trump's tweet thanking Phantom Fireworks and Me personally for donating this year's fireworks for the Washington D.C. show."

Zoldan said that as of 10:50 p.m. nothing had been found at the site.
