BELLEVUE, Wash. — Bellevue Police arrested one protester Tuesday after police said he intentionally attacked a bike officer in downtown Bellevue.

The incident was isolated from the protest that took place outside a Bellevue hotel that was hosting a police appreciation dinner.

Other than the one arrest, Bellevue Police spokesperson said they were pleased that no businesses were damaged and nobody was injured in a protest that lasted roughly three hours.

Around 8 p.m., roughly thirty protesters in black converged on a group of police supporters outside the Hyatt Regency.

The dinner was organized by the Billy Graham Evangelistic Association.

At one point, the group of protesters in black lit something on fire along Bellevue Way. Police tweeted it was a flag.

Law enforcement officers in Bellevue as well as local businesses were on alert Tuesday evening for the possibility that protests over an appreciation dinner thrown by prominent Evangelical leader Franklin Graham could turn chaotic.

As of 7 p.m., up to a dozen demonstrators held signs and standing outside the Hyatt Regency Bellevue, located at 900 Bellevue Way NE, which was hosting the event.

A contingent of bicycle cops were seen riding through the city and several officers stood outside the hotel entrance, according to live pictures from Air 4.

Bellevue police posted messages on the department's website and social media channels about the protest scheduled for 7 p.m. at Bellevue Downtown Park. The agency has enlisted help from nearby law enforcement agencies if they need backup, officials said .

"The rhetoric in there is encouraging people to bring projectiles," said police Maj. Andrew Popochock. "And (engage in) activity that would be against the law."

The Billy Graham Evangelistic Association invited several local law enforcement agencies to attend the dinner, which they said was being held to show their appreciation.

"This is not a taxpayer-funded event," a spokesman for the religious group said in a written statement. "This dinner and event are a gift from the Billy Graham Evangelistic Association and from Christians all across this country who want these men and women to know they are appreciated."

Bellevue police said outside groups may use the event as a reason to be destructive in spite of the sentiment behind the dinner.

Charlotte LeFevre, representing Capitol Hill Pride, was among the first to rally outside the high end hotel Tuesday, saying she wanted to create awareness and advocate for the LGBTQ community. She said the religious group behind the free dinner for police is not inclusive.

"it is an affront and offensive to the LGBTQ community," she said.
