As Kenya's Kipsang, 31, approached the finish in front of Berlin's iconic Brandenburg Gate, for a new world record of 2 hrs 3 mins and 23 secs, he was briefly joined by a man in running kit and a race number.

The intruder was chased by race staff in the finish area before being handed over to police.
A Berlin police spokesman confirmed that the man has been charged with trespassing and has subsequently been banned from future events run by the Berlin marathon's organizers.
