In a press conference Friday, Brian Valenti, Chief of the Covington Police Department, broke down the moments inside a clash between demonstrators and police Thursday that led to the arrest of 18 people.

Cincinnati protest for a detained chaplain led to confrontations, multiple arrests, and a temporary restraining order for the chaplain.

Opinion: What happened to Imam Ayman Soliman, and what happened on the Roebling Bridge, is a betrayal of American's promise of liberty and justice.

As Soliman supporters gathered to protest what they consider his unjust detention, "another level of injustice occurred in front of people's eyes," said Rev. Nelson Pierce Jr., senior pastor of Beloved Community Church in Mount Airy.

The demonstration started as a vigil for a man detained by ICE after suddenly having his asylum status revoked.
