The first robbery happened last Wednesday just after 9 a.m. Police say group of six men cornered a teenager in an alley behind the Beacon Hill library and robbed him of his backpack, phone and bank cards.
Early the next morning, a car full of men drove up to a woman near 56th and Latona and demanded the woman's purse, according to police. When the woman refused, police say the robbers got out of the car, flashed a gun and took her purse.
Later that night, police say the same group of robbers pulled a knife on a delivery driver in Holly Park and stole four pizzas. Just a half hour later they struck again in West Seattle, robbing a man of his iPhone in the 5500 block of 16th Avenue SW.
In the early hours of August 2, the robbers grabbed a 28-year-old man near Harvard Avenue and East Thomas on Capitol Hill. They put the man in a headlock and stole his iPhone and wallet, according to police.
The next morning, police say two robbers and a lookout approached a pair of men at 11th Avenue and East Pine near Cal Anderson Park. One of the men pulled out a gun and robbed the victims of their wallets and phones.
A half hour later, two robbers climbed into a man's car outside of a Central District hookah bar. The robbers drew their guns on the car's owner and forced him to drive to Renton, where they pistol whipped him and stole his wallet.
Detectives believe the same group snatched a woman's purse near Senaca and Broadway at about 3:45 a.m. on August 4.
Police have not released detailed descriptions of the robbers, but say they may be East African or Somali and may be driving a green Toyota Camry.
