Two teenagers have been charged with weapons offences after a stop-and-search over a 'ticket issue' in London Euston revealed the pair allegedly carrying two enormous machetes.

Disturbing footage captured in the Underground area of the station yesterday afternoon shows the moment British Transport Police (BTP) arrested the youths after discovering the terrifying blades.

BTP said they had the grounds to establish a search over the ticketing problem but their probe uncovered the huge weapons.

In the horrifying video which lays bare the size of the knives, the tracksuit-clad youths can be seen hanging their heads as a woman and a small child walk past.

Officers quickly arrested the pair, aged 15 and 16, and took them into custody before they were both 'further arrested on suspicion of breach of court bail as part of an unrelated matter'.
