Gunmen stuck up a lottery vendor just north of Hospital San Juan de Dios Wednesday morning and then wounded a policeman and a relative of the victim.
Other police officers on bikes chased suspects on a motorcycle and caused their arrest a short time later. But the Judicial Investigating Organization reported later that the pair were not involved in the robbery and shooting.
The crime took place at Plaza Rofas, which is on Calle 16 a short distance from the hospital’s emergency entrance.
The 30-year-old woman, Victoria Brenes, had come to the city from San Antonio de Escazú by bus and carried 800,000 colons to make Christmas purchases, police said.
Two policemen nearby intervened in the robbery, and one, identified by the last name of Quirós, suffered a bullet wound to the knee. The robbers fled but not before relatives of Ms. Brenes chased them. One relative, identified by the last name of Gómez, also was shot.
Four police officers on bikes chased motorcycle riders in the belief that the two were the robbers. They managed to identify the motorcycle so that other officers detained the pair in La Uruca. The Judicial Investigating Organization said later in the day that the pair had been cleared.
During the daytime there are about 36 police officers on bikes in the downtown.
The crime resulted in a blockade of major streets and caused delays for persons headed to work in the morning.
