This story occurred somewhere around 2000 but the location is in Hong Kong.
The protagonist was another DJ from a local radio station. It was during an aired program known as the '4 columnists' (四人夜话):
DJ: "I believe you have some story to tell?"
Caller: "Yes. I think the house opposite mine is haunted."
DJ: "Why do you think so?"
Caller: "The house I meant has seen a suicide case 200 years ago. A woman hung herself on the central beam and her restless spirit has haunt that house since then...
After her death, I have seen the hung ghost wandering about in the house protruding her slimy long tongue. I was being licked once on the face one night when I ventured into the already abandoned house to ghost hunt.
Then I felt a noose was put around my neck and a fore pulled the noose upwards and I was forced to accompany this hung ghost until now... It was the year 1800 when I was murdered... He... He... He..."
DJ: "Look.We welcome you to share your story but you must not take this advantage to tell pranks!"
Caller: "Wow.. wow... wow..."
And following a series of eerie crying sounds, the line was cut.
Of course, the above story sounds more or less like a prank call indeed. I just pull out and posted it here for your comparison purpose. Perhaps, the Karak Highway story is more believing?
