DARTMOUTH - Canada Day celebrations at Alderney Landing were interrupted by police after a series of physical disturbances broke out.

Just before 10 p.m. Halifax Regional Police responded to a call in the area where thousands were gathered for the annual free Canada Day concert.

Police say while they were placing one man under arrest, a 17-year-old male was also arrested for allegedly obstructing the arrest.  

The second man was found to have a knife and will face charges of possession of a weapon dangerous to the public and obstruction.

He was released and will appear in court at a later date.
