A Bridgeport, Connecticut, man was arrested after calling 911 and threatening police on Friday, according to the incident report.
The dispatch center at State Police Troop G in Bridgeport received a 911 call from Alexander Rosa, 28, of Bridgeport, "warning all police officers that if they kept killing people, [the police officers'] mothers, daughters and sons were all going to be killed," according to state police.
State police arrested Rosa at 10:30 a.m. on Friday, charging him with second-degree threatening, second-degree harassment and failing to submit finger prints.
He was held on a $50,000 surety bond and released to judicial marshals custody to be arraigned in court that day.
The arrest comes on the heels of nationwide protests responding to the choke-hold death of Eric Garner and the fatal shooting of Michael Brown, but state police did not say if Rosa is suspected of making a threat due to the protests.
