Police investigating the disappearance of an Irish student in Glasgow have detained a 21 year-old man, BBC Scotland understands.

Karen Buckley, 24, from Cork, was last seen leaving the Sanctuary nightclub with a man in the early hours of Sunday.

Police Scotland confirmed officers are following a "definite line of inquiry".

High Craigton Farm near Milngavie has also been cordoned off as part of the investigation.

Officers have been searching Dawsholm Park, where Miss Buckley's bag was discovered on Tuesday.

Miss Buckley arrived at the Sanctuary nightclub with friends at about 23:45 on Saturday and at about 01:00 she told them she was going to the toilet. She failed to return and did not take her jacket.

Her friends have said Miss Buckley had had a few drinks, but was not drunk.
