West Yorkshire Police has launched an investigation - with officers "providing reassurance and safety advice to affected schools".

In messages to parents, one primary headteacher said police had been treating the threat as "credible" - and children were being kept indoors for the whole day, with gates locked and windows and doors closed.

In its statement, the force said: "Police are aware of an email which has been sent to a number of schools in West Yorkshire today."

According to Leeds Live, the schools understood to be affected so far are Richmond Hill Academy, Ruth Gorse Academy, Sharp Lane Primary School, Windmill Primary School, Beeston Primary School and Clapgate Primary School.

Several schools in Leeds have not been issued an email but have bolstered their security measures to provide reassurance to parents and caregivers.

The schools implementing a soft lockdown have communicated that students will be required to stay indoors throughout the day, while certain students might be sent home from school early.

Students left Sharp Lane Primary School as normal on Thursday afternoon in what was understood to be a moment of real concern. Parents and teachers discussed what had happened at the school gates.

Schools are expected to continue as normal tomorrow.

A Leeds City Council spokesperson said: "We are aware of an ongoing situation relating to emails received by a number of schools in Leeds and we are working closely with West Yorkshire Police to monitor the situation and provide support to schools."

Meanwhile, a Bradford Council spokesperson said: "We are aware that a number of schools in West Yorkshire, including the Bradford district, received an email today which is being investigated by the police.

"Police officers are providing reassurance and safety advice to affected schools.

"We are supporting our schools as they follow this advice. The safety of everyone in our schools is of course our top priority."

'There is no threat to our site'

Gildersome Primary School posted on Facebook on Thursday afternoon, saying staff are being "extra vigilant" and normal "safeguarding procedures are being followed".

The school said it was "not in lockdown".

"To reinforce, there is no threat to our site, we are just being extra cautious as advised by the local authority.

"This is being investigated by police and officers are providing reassurance and safety advice to affected schools."

Earlier this week, a police investigation was launched after malicious emails were sent to a number of schools in the North West.

One parent told Sky News that she was "petrified" after she was told - and that it reminded her of incidents affecting schools in the US.

A school in Chester went into lockdown and prevented parents from picking up their children - but later said the "unpleasant email" it had received was "believed to be a malicious hoax".

Blacon High School, also in Chester, said it had put additional measures in place after receiving the email, but added: "For reassurance, Blacon High School is not currently in lockdown."
