Update - 9.41pm: A woman who was attacked with a drill in the North remains in a critical but stable condition in hospital tonight.
A teenage boy was arrested after the 38-year-old woman suffered a "very serious" head injury, police said.
The victim is in a critical but stable condition in hospital after the attack, described as "barbaric" by local representatives, in County Tyrone.
Corey French, who described himself as a family friend, said he spoke to the victim at a local nightclub just hours before the attack.
The 24-year-old, said: "She was (having) good craic, we were having a laugh, chatting away."
He described the woman as someone with a "complete and utter heart of gold".
He added: "She wouldn't be the sort of person who would be confrontational, she would be very friendly."
Local politicians have expressed their disgust.
Sinn Féin West Tyrone Assembly member (MLA) Michaela Boyle said people are shocked at the "horrific" nature of the attack.
She added that, if there does turn out to be a homophobic motive behind the assault "then this barbaric attack is all the more reprehensible".
Fellow MLA Daniel McCrossan added his voice to the outrage, and called for those with information to come forward.
The SDLP representative said: "I am absolutely horrified by this assault. This kind of sickening behaviour has no place in society."
