The gunmen were said to have stormed a disputed land where some people were busily working and started shooting sporadically.
They also succeeded in setting ablaze some container shops and a vehicle on the said disputed land before leaving the scene, residents say.
The disputed land is believed to be owned by the Ghana Road Transport Union but a private developer is also laying claim to it.
