Officers from the 107th Precinct have stepped up their patrols with a new sense of urgency.
Detectives have released surveillance images of the three suspects.
Police say the victims were attacked moments after they stepped off the bus near Union Turnpike in Fresh Meadows.
The suspects approached the victims from behind and, in some cases, punched and kicked them before stealing cell phones, iPods, Blackberries and cash.
The bus stop bandits struck first on October 20 at 9.40 p.m. and again the next day. They then struck two weeks later, and just this week have struck four more times. Police say three of those four were Wednesday night, bringing the total to seven.
Detectives say they are determined to make arrests before they strike again.
Investigators say four of the victims were women and three were men.
Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS.
