The Dallas motorcycle police officer who was injured in an accident during President Barack Obama's motorcade Monday was released from the hospital on Tuesday morning.
Senior Cpl. Michael Manis was part of the president's police escort from Dallas Love Field to a private Democratic fundraiser in Highland Park when the accident happened just after 4 p.m. on Monday.
Dallas Police Chief David Brown said Manis was part of an "advanced leapfrog" formation in which officers trade positions leading the presidential motorcade through intersections when the crash happened in the 2900 block of Wycliff Avenue at Hartford Street in Dallas.
"This is just a minor accident with minor injuries," Chief Brown said. "Officer Manis will be fine."
Brown said Manis hit his head and suffered abrasions to his elbows and hands.
Manis was in good condition Monday night and will be kept at Parkland Hospital overnight for observation. Doctors have ruled out a concussion.
Manis' wife and three children joined him at the hospital.
"Obviously, they were shook up a little bit from the indications early on that he had an accident, but once at the hospital, they saw his condition, (and) they were very much relieved," Brown said.
Brown told reporters outside Parkland Hospital that his department had witness accounts that Manis' motorcycle tumbled, information consistent with the investigation so far.
"I think he wanted to speed up, and he jerked up his front wheel and hit the accelerator, and the thing just flipped up like that," witness Barry Hutchings said.
Witnesses said a doctor in Obama's motorcade stopped to help as they waited for paramedics to arrive.
Dallas police will investigate the crash to determine exactly what happened. Brown said investigators would be talking to officers and citizens who saw the incident.
Manis is a veteran Dallas police officer who joined the department in June 2001 but had only been a motorcycle officer for six months.
This is not the first motorcade crash involving a Dallas Police Department motorcycle officer.
On Feb. 22, 2008, Senior Cpl. Victor Lozada was killed in a crash just moments before Hillary Clinton, then a U.S. senator from New York running for the Democratic nomination for president, passed by during a campaign stop in North Texas.
Clinton, who is now the U.S. secretary of state, immediately canceled all events for that day to be with Lozada's family.
After Lozada's death, the Dallas Police Department put new rules in place that require motorcycle jocks to practice their route prior to an assignment.
"We're constantly evaluating our use of motorcades, and only when absolutely necessary do we implement motorcades," Brown said.
