San Francisco Police are a little edgy, the local Fox affiliate reports, after a string of armed robberies happened in a span of about three hours Tuesday night night in Russian Hill and Telegraph Hill. All told, there were six total armed robberies across town last night.

According to KTVU, the three robberies that appeared to be connected started around 1:15 a.m. on the 1500 block of Union Street near Van Ness:

Police say two men- described as Hispanic and Hispanic and/or Black, ages 20 to 30 years old- exited a four-door sedan and robbed the male victim at gunpoint.

Two hours later and just a few blocks away, police said suspects matching the same description drove up to a 22 year-old man and 17 year-old girl walking near the intersection of Broadway and Hyde Streets.

About fifteen minutes later in Telegraph Hill at Kearny and Vallejo Streets, the same suspects allegedly robbed a 22-year-old victim as he was walking.

According to SFPD spokesman Officer Albie Esparza, in each case the suspects hopped out of the car and brandished a weapon before robbing and assaulting the victims and tacking off. "Typically what we see is people gather the property and flee," Officer Esparza explained. "In this case, these suspects are very bold and brazen."

According to SFPD, three other armed robberies happened between Tuesday night and Wednesday morning, which they say were not related, but may have been a result of the warmer weather that draws out the late night crowds and opportunistic criminals.
