LONDON (AP) — Thames Valley police said a British police officer investigating a reported burglary has been killed.

Ten males have been arrested and are in custody, including a 13-year-old.

Prime Minister Boris Johnson said he is “deeply shocked and appalled” by the death of Thames Valley Police Officer Andrew Harper. Johnson said in a tweet that his thoughts are with Harper’s family, friends and colleagues.

Johnson said Harper’s death “is the most powerful reminder that police officers up and down the country put themselves at risk every single day to keep us safe. They have my absolute support”.
