Police say the women -- two adults and a teenager -- were arrested early Wednesday on suspicion of robbery, among other things.
The women are accused of jumping people and stealing their cell phones in Downtown Seattle and around Seattle Center.
One robbery was reported in the 500 block of Broad Street just after midnight, and another was reported near Second Avenue and Pike Street just before 2 a.m., according to police.
A victim from the Second and Pike robbery flagged down an officer and told him three women had stolen her cell phone. The victim then pointed out the robbers, who were at a nearby bus stop.
Police searched the women and found a number of stolen cell phones. The two adults were arrested and booked into King County Jail for investigation of robbery and warrants.
The teen had a no bail warrant for her arrest. She was booked into the Youth Service Center on her warrant and two counts of possession of stolen property.
