Acting President Lee Ju-ho visited the police and firefighters on Saturday to inspect public safety ahead of the Children's Day holiday next week.
Lee encouraged police officers and firefighters during visits to the Hwayang police patrol unit in Seoul's Gwangjin Ward and the Gangdong fire station in eastern Seoul.
The Hwayang unit oversees Seoul Children's Grand Park, which is expected to draw many family visitors for May 5 Children's Day and the extended holiday through Tuesday.
Lee instructed the police officers to pay special attention to crowd safety measures.
At the fire station, he inspected fire prevention and accident response measures following the Gangdong sinkhole accident in March that swallowed a motorcycle driver.
"In the event of a sinkhole appearance, the first report will be received by the firefighting agency, so promptly take traffic control and other first response measures together with the police, the local government and other related agencies to ensure no casualties," Lee was quoted as saying.
