BOGOTA, June 8 (Reuters) - Colombian Senator Miguel Uribe, a potential presidential contender, survived an initial operation for his injuries after being shot in Bogota on Saturday, according to his wife and the hospital treating him, although he remains in intensive care.

Uribe, 39, is a member of the opposition right-wing Democratic Center party and was shot in the head during a campaign event in a public park in the Fontibon neighborhood.

A boy under 15 years of age was arrested after the shooting, the attorney general's office said in a statement on Saturday, adding he was carrying a 9-millimeter Glock-type pistol.

The government said it is investigating if there were other potential perpetrators. Leftist President Gustavo Petro urged an investigation into who had ordered the attack in remarks late on Saturday.

Campaigning is just beginning for the country's 2026 presidential election and Uribe, who is from a prominent political family, does not have a well-known platform so far.
