The area around the cemetery was cordoned off following reports of an assault.
This cordon remained in place for much of the day and has since been lifted, the force confirmed on Sunday.
The victim, an 18-year-old man, was taken to hospital where he was treated for head and arm injuries. His injuries are not believed to be life-threatening.

The first is described as a white man, of large build, with blond hair. He was wearing a tight black top and light blue jeans.
The second suspect is described as a white man, with blond hair. He was wearing a blue hoodie and light blue jeans. Both men are described as being around 20 years of age.
