A memorial to two UDR soldiers murdered by the IRA has been defaced only hours after a prayer service was held to remember them.
An IRA poster was erected and two remembrance crosses removed from the scene at Corgary Road in Castlederg.
The memorial marks the deaths of Norman McKinley and Heather Kerrigan, who were killed in a landmine attack in 1984.
A number of wreaths were damaged at the site, and a poster with the words 'IRA 2 UDA 0' erected.
It's understood crosses had been laid on Monday, marking 30 years since the attack.
PSNI chief inspector Andy Lemon condemned the incident.
"We are investigating this as a hate incident and have seized the poster," he said.
"Incidents of this kind do nothing for community harmony in the area, indeed I believe the vast majority of people in and around Castlederg will be appalled by what has happened."
