A Spanish man who according to friends 'confronted' a terrorist who was stabbing a woman has gone missing.

Friends, family and the Spanish Red Cross have put out messages on social media, asking for the safe return of the HSBC worker.

According to his brother, the brave missing man fought off a terrorist using his skateboard.

His brother wrote on Facebook: "He was seen fallen down after defending a woman with his skate[board]."

Ignacio Echeverría, a 39-year-old who lives in London, has not been traced by his family in Madrid since he was on his way home after skating in a park with his friends when they saw one of the terrorists stabbing a woman near Borough Market.
