French prosecutors say authorities have arrested the suspected gunman in a shooting at a Paris newspaper that gravely wounded a photographer.

Agnes Thibault Lecuivre, a spokeswoman for the French prosecutor's office, said that "a suspect with a strong resemblance to the shooter" was arrested Wednesday evening. The suspected gunman is also believed to be behind three other attacks around the capital.

The arrest took place in Bois-Colombes, 6 miles north of Paris. Lecuivre says she cannot give further details.

Authorities had released video footage and photos of the suspect nationwide.

The motive for the attacks is unclear. They prompted heightened security at media offices and on the busy Champs-Elysees shopping avenue.
