Father forces daughter to take lie detector test after she was expelled from school

A fuming father forced his daughter to take a lie detector test, because she claims she was wrongly was excluded from her grammar school for putting crushed nuts on an allergic teacher's desk. Alexandra McDonald was excluded for 20 days alongside pal Maddie Colley after they were accused of leaving crushed nuts in the classroom of a teacher who has a severe allergy. But the Rochester Grammar School students insist they have been framed. Alexandra's dad Peter McDonald believed his daughter so much he shelled-out almost £600 for experts to give her a Jeremy Kyle-style lie detector test - that found she was telling the truth.
