Police were told the bombs were going to go off within minutes, with the caller claiming they had planted the devices an hour and a half before the event was due to start
Police received calls an hour before Jake Paul and Tyron Woodley took to the ring on Sunday night saying bombs had been planted at Rocket Mortgage FieldHouse, according to reports.
The call was made around 10.15pm, reports TMZ, and informed police that pipe bombs had been placed underneath the ring and in the bathrooms of the arena in Cleveland.
Police were told the bombs were going to go off within minutes, with the caller claiming they had planted the devices an hour and a half before the event was due to start.
The report adds that the caller told authorities to evacuate the arena, which was held around 16,000 fans, because the bombs were about to be detonated.
A bomb unit was dispatched, with specially-trained dogs brought in to sweep the building.
No bombs were found, suggesting the call was an empty threat.
A police spokesman told TMZ that no arrests have yet been made but that their investigation is ongoing.
Paul secured a split decision victory over Woodley on Sunday night as he went the distance for the first time.
The 24-year-old YouTuber, who has come out on top in his previous four fights within two rounds, won 77-75, 75-77, 78-74 on the scorecards.
Paul was rocked in the fourth round when the former UFC champion sent him into the ropes.
But Paul rallied to maintain his unbeaten record.
“Me and Jake need to run it back. I want a rematch. I feel like I won,” Woodley said after the contest.
“If you get a tattoo ‘I love Jake Paul’ then we will run it back,” responded Paul, to which Woodley agreed.
