LIGHTNING struck at a school in Amersham during last night’s thunderstorm, playing havoc with its phone lines.

Although it is open as normal today, Dr Challoner’s Grammar School in Chesham Road has advised parents to use alternate means of contacting the school if necessary.

A statement on the school’s website says: “Due to a lightning strike at the school we have received severe disruption to our telephone services.”

The statement goes on to advise that anyone who needs to contact the school urgently should do so via a mobile number, given on its website at www.challoners.com.

All non-urgent contact should be undertaken via the email: admin@challoners.com
