Five female students are under observation in hospital tonight, after they apparently failed to screech like harpies on their walk home.
The un-named women are being studied by psychologists at the University Hospital Coventry and Warwickshire. They'd spent the night drinking vodka and Red Bull at 54, Coventry University's Union bar and left just before 11.
"They were knocking the booze back with no problem." barman Dave Middleton told reporters "They left just before we closed and we only got involved when the Police contacted us. Apparently their behaviour was creating a problem on their route home."
Inspector Tracey McDonald confirmed the group had been detained. "We got involved when a concerned resident notified us that contrary to their usual behaviour, this group were making their way home without screaming at the top of their voices, yelling drunkenly into their mobile phones and shouting sexually explict remarks at groups of random men."
A Tactical Support Unit from the city's Little Park Street station was dispatched to deal with the group, who're being held in isolation at the city's hospital.
A spokesman for the NHS Trust said the women, all aged between 19 and 22, were under observation while experts from the City Council searched their Hillfields home for possible environmental factors that could explain their behaviour.
