(TELEGRAPH) — Two primary school boys have been disciplined after spiking a teacher’s coffee with a “home-made concoction” thought to contain bathroom products – but will face no charges.

The children poured the substance into a flask on the teacher’s desk while her back was turned, but she was warned before taling a sip.

Clapham Terrace Community Primary School in Leamington Spa, Warwickshire, declined to say what punishment had been given to the boys involved in the incident.
