San Francisco police have arrested two suspects believed to be tied to a trio of violent robberies in the city stretching back to late July.

On Thursday, the SFPD announced that 21-year old Daisy Rodriguez and 19-year-old Fernando Herrera, both of San Rafael, had been charged with nine felonies in connection with three separate robberies at knifepoint.

The Police Department’s announcement was not clear about when the arrests took place.

According to police, the first robbery occurred at around 5 a.m. on July 27 on the 3100 block of Mission Street. When police arrived at the scene they found a 48-year-old man had been robbed and stabbed in the torso. The man was treated at a nearby hospital and later released.

A month later, while police were still investigating the Mission Street incident, a 26-year-old female San Francisco resident was robbed at knifepoint near Church and Clipper streets.

Four days after that, the duo struck again, police allege. A 29-year-old female resident of Edina, Maine, was robbed and stabbed near Broderick Street and Golden Gate Ave. on Aug 31 at around 2:15 a.m. The woman sustained lacerations on her face and was treated at a nearby hospital and released. police said.

Investigators followed a series of leads that led them to Rodriguez and Herrera in San Rafael, where they were located and arrested.

SFPD Officer Joseph Tomlinson said Monday that police were still investigating whether the duo are tied to other robberies. Anyone with information is asked to call the SFPD 415-575-4444 or Text-a-Tip to TIP411
