A PSNI officer has died suddenly in Co Tyrone.
Detective Inspector Alanna Moore, a mother-of-one who was from the Dungannon area, was described as a "valued colleague" who possessed "great skill and understanding".
Police have said her death on Wednesday is "not being treated as suspicious at this time".
In a statement the PSNI confirmed they attended a report of a sudden death in the Ballynakilly Road area of Coalisland.
A spokeswoman for the Police Ombudsman said on Friday that it "has received no referrals" about the incident.
Liam Kelly, chair of the Police Federation, paid tribute to the experienced officer.
"The loss of a valued colleague is keenly felt by her immediate work colleagues and the wider service," he said.
"She was a mother, an experienced officer and someone who possessed great skill and understanding.
"She will be sorely missed. Our sympathies are extended to her family in this time of great loss."
SDLP Policing Board member Mark H Durkan also offered his sympathies.
"I am saddened to hear of the sudden death of a serving police officer in the Coalisland area.
"My thoughts are with her family, friends and PSNI colleagues at this difficult time."
A death notice described Ms Moore as a "beloved daughter" and "dear sister", adding that she will be lovingly remembered and greatly missed by her family.
