Police are appealing for public assistance following a number of incidents in Brisbane City in the early hours of this morning.

Initial investigations suggest at 1:50am a group of men assaulted a driver from a ride sharing company before grabbing his mobile phone as he sat in his vehicle on Wickham Street in the Fortitude Valley.

A short time later at 2:30am a group of men allegedly assaulted another man sitting in his car on Wickham Street, punching him and damaging his vehicle.

At around 3:15am, a second ride sharing company driver was assaulted by a group of five men on River Terrace at Kangaroo Point. The men assaulted the driver before damaging his car. The 49-year-old man was treated at the scene for cuts and bruises to his head.

Police believe the same group of men may be involved in all three incidents.

Police investigations are continuing.
