Security has amped-up its coverage and is under review after a 40-year-old woman was arrested on suspicion of attempted burglary.

A Met Police spokesperson confirmed that they would be working closely with the school to identify exactly how the woman was able to gain access to the grounds.
"We are working with the school, which is attended by His Royal Highness Prince George, to review its security arrangements after the incident," the spokesperson said.
"Police are part of the protective security arrangements for the Prince and we will continue to work closely with the school, which is responsible for building security on its site."
About 560 children between the ages of four and 13 attend the private school where feeds start at about £17,604 a year ($20,927.46 USD).
A spokesperson for Kensington Palace confirmed with the Mirror that "Prince George was at Thomas' Battersea School at the time of the arrest at 2:15 p.m."
While he was at school at the time of the incident, the palace confirms that he will continue attending school as normal.
The unidentified 40-year-old woman was taken to a South London police station where she remains in custody.
