Cambridge Police are warning residents to be vigilant after six people have been victims of armed robberies in a 28-hour period.
Police presence will be increased as a result of the robberies in the mid-Cambridge, Inman Square and East Cambridge areas, said Dan Riviello, a department spokesman.
“They’ve been armed robberies, but no one has been injured and we want to keep it that way,” he said.
The most recent robbery occurred last night about 11:53 p.m. near Cardinal Medeiros Avenue and Marney Street when a man was approached by two men who stole the victim’s bag and fled.
About 10 minutes before that, a man walking alone near Harvard and Dana streets was approached by two men who showed a gun and demanded his “stuff,” police said. The man gave the robbers his laptop, money and cell phone.
Three other similar incidents took place Monday evening and early yesterday.
It is believed at least four of the robberies are connected, but police are still investigating.
Police have warned residents to not resist if they are robbed, be aware of your surroundings when walking, don’t walk with earphones or listen to music when walking alone and to always walk with a friend or in groups if possible.
Since yesterday, police have been sending alerts and safety measures about the robberies to residents who have signed up on the city’s alert network.
The alert network launched in August and allows residents to sign up for three systems that will alert them to emergency situations like evacuations, neighborhood crime alerts and city service notifications like street sweeping.
“It’s very important to get this information via cell phones or e-mails because that’s how people communicate these days,” Riviello said.
Anyone with information on the robberies can call 617-349-3300.
