LONDON (AP) — British police were called to the London home of prime ministerial contender Boris Johnson after a neighbor reported an altercation.

The Metropolitan Police force says officers were called in the early hours of Friday to the home Johnson shares with partner Carrie Symonds by someone "concerned for the welfare of a female neighbor."

The Guardian newspaper said neighbors had reported hearing screaming, shouting and banging.

Police said officers found that all occupants were "safe and well" and no offenses had been committed.

Johnson is favorite in a two-person race to become leader of the Conservative Party and Britain's next prime minister.

Last year, he and his wife Marina Wheeler separated after 25 years of marriage.

Johnson's spokesman didn't immediately respond to a request for comment.
