Three teenagers have been bailed after they were arrested in connection with a spate of car-jackings in Birmingham.
The 16-year-old boys were arrested on Wednesday in raids by West Midlands Police, who are investigating attacks in Moseley and Kings Heath in February.
Officers also seized cash, a car key, mobile phones and clothing. They believe the attacks were planned on the messaging service WhatsApp.
The boys have been bailed while investigations continue.
