Detective Superintendent Danny Doherty said two teenage boys were assisting police in the investigation into the death of a Canberra man whose body was found at Broulee on February 2.
"The circumstances were considered suspicious," he said.
At press conference in Sydney on Thursday, February 13, Detective Superintendent Doherty said the alleged use of dating apps was being investigated.
He said police would allege a teen had communicated with Mr Keeley via a dating app.
He said both teens were likely to be charged with murder after search warrants were executed at homes in Broulee and Tomakin on Thursday morning.
He said to his knowledge neither youth had a criminal history.
Meanwhile, the family of Mr Keeley released the following statement through police:
"Our family is devastated and still coming to terms with the fact we have lost Peter," the family said.
"All that can be said is we have been deeply affected by this tragedy and we are still grieving.
"We are grateful for the overwhelming support from family and friends.
"Thank you to the NSW Police Force and ACT Police detectives who have supported our family during this terrible time.
"As we continue to process this news, our family has requested privacy at this time to allow us to support Peter's children."
Police on Thursday morning said they had arrested two teenagers in the Broulee area as part of an investigation into the death of a man whose body was found in the area on February 2.
Two 17-year-old boys were arrested and taken to Batemans Bay Police Station.
About 4.50pm on Sunday, February 2, 2020, emergency services were called to bushland near McNee Street at Broulee, following the discovery of a man's body.
He has been formally identified as 56-year-old Canberra resident, Peter Keeley.
Police said a post mortem examination was inconclusive; however, Mr Keeley had suffered head and facial injuries.
Detectives from the State Crime Command's Homicide Squad and South Coast Police District established Strike Force Henrick to investigate the circumstances surrounding his death.
Police said Thursday's raids followed extensive investigations and a public appeal last week.
