Prosecutor José Olivares-Chandler said: 'There were two elderly Polish occupants in a downstairs bedroom of this residential premises.

'There were woken by noise and it became clear there was a stranger at the window.

'The male occupant saw an arm, shouted and disturbed that stranger who ran off across the front garden, through the gate and away.'

The elderly couple slept in a ground floor bedroom which overlooking their front garden.

Despite being woken by Farah they did not see him but his fingerprints were found on the window.

The prosecutor continued: 'He was arrested at a later date after details were circulated and gave no comment during interview.'

The court heard how Farah, who lived in Brentford, west London, had a string of previous convictions including two for burglary.

Mr Olivares-Chandler said: 'Your honour will see that he has 15 convictions for 20 offences.

'There are numerous offences for dishonesty, but the two the Crown would like to draw reference two are domestic burglaries.

You are 21 years of age and you have got an unimpressive criminal record. Judge Jones, Kingston Crown Court

He pleaded guilty to one count of attempted burglary with intent to steal after prosecutors agreed to drop a more serious charge of burglary with intent.

Andrew Turton, defending, claimed he was an 'opportunist' who had seen the chance to break into the property after visiting his girlfriend nearby.

He said: 'On the same road lived his girlfriend, this was an opportunist, spur-of-the-moment burglary.'

Sentencing him to 15 months imprisonment Judge Jones said: 'You are 21 years of age and you have got an unimpressive criminal record.

'Apart from matters of theft you have two previous residential burglaries and you have offences of robbery and handling stolen goods - not an attractive record [and] have been in custody for a fair amount of time.
