Woman arrested on suspicion of attempted burglary at Prince George's London school: Police George, 4, started at Thomas's Battersea School in September.

 -- A 40-year-old woman has been arrested on suspicion of attempted burglary at the London school attended by Prince George, according to police.

The woman, who was not identified, was taken into custody today after trying to access Thomas’s Battersea School on Tuesday, the Metropolitan Police Service said in a statement.

George, 4, began attending the private school in Battersea, South London, last week. He was escorted to his first day of school there by his father, Prince William, and Helen Haslem, the head of Thomas’s lower school.

"We are working with the school, which is attended by His Royal Highness Prince George, to review its security arrangements after the incident," police said. "Police were alerted and officers attended immediately after the issue came to light."

The suspect remains in custody at a South London police station.

Thomas's Battersea has approximately 550 students from a variety of backgrounds — whom George will one day lead as king. The approximately $23,000-per-year school teaches a range of traditional subjects, along with ballet, art, drama, French, music and physical education.

George, whose parents are the Duke and Duchess of Cambridge, is known as George Cambridge to his classmates.

The Metropolitan Police Service are part of the security force for members of the royal family.

The police said Thomas's Battersea is responsible for building its own security but pledged to continue to "work closely" with the school.

A spokesperson for Kensington Palace told ABC News, "We are aware of the incident but cannot comment any further."
