The moment a suspected stalker, 40, was arrested trying to break into Prince George's new school for the SECOND time in 24 hours after police sting 'involving undercover officer'

The woman was sitting outside Queenswood restaurant (left) in Battersea Square with two men, one believed to be an undercover police officer, when the arrest operation began. At 2.20pm, an unmarked police car sped into the square followed by a police van which stopped outside the restaurant. Three police officers, two male and one female, spoke briefly to the woman. She was then searched by the female officer before stepping into the back of the van (ringed, left inset). She remained composed throughout and did not remonstrate with the officers. One eyewitness, who was eating at the restaurant, said: ‘She was completely calm and passive. She seemed completely unfazed.’ Teachers at Thomas’s London Day School were on red alert after the same woman had been able to briefly talk her way into the building posing as a legitimate visitor 24 hours earlier. She escaped when challenged by staff but was spotted again loitering nearby yesterday afternoon triggering her arrest on suspicion of attempted burglary. The prince (right inset), four, who is third in line to the throne, was not present at the time of either security scare because as a new starter he leaves at lunchtime.
