The youngest member of popular Britain's Got Talent dance act Stavros Flatley has been arrested after a police drugs bust.

It is alleged that officers found a cannabis factory worth £56,000 in the north London flat of Lagi Demetriou, 20, who appeared on the talent show with his father Demetri, in 2009.

Firefighters are reported to have stumbled across a watering system for 460 plants at the property in Enfield, when they were investigating reports of a leak.

Lagi and Demetri charmed audiences with their bizarre 'Greek Riverdance' routines and it is believed that the son, who was 13 when he appeared on BGT, used the money earned during his time in the spotlight to buy the £295,000 flat.

However, it is not believed that he lives in the property.

A friend told the Sun that Demetri was devastated when he heard of his son's arrest and broke down in tears.

He said: 'He burst out crying when he heard.

'Demetri's 100 per cent against drugs and will be furious about this.'

The pal also claimed that Lagi and his father own a number of properties in the Enfield area.

He also said that Lagi works as a barber when he is not dancing with Demetri.

The friend added: 'He has told the police that his mate was a tenant there.

'He said he doesn't know anything about the cannabis-growing operation. '
