A prolific gang of thieves who carried out early morning raids on multi-million pound mansions to steal cash, jewellery and luxury cars have been jailed for a total of 17 years.
Mohammed Alam, Sayed Juied and Sadek Miah treated burglary 'like a job, a profession,' raiding houses in affluent west London, Herfordshire and Surrey.
Over the course of 11 months the gang broke into 21 homes, taking a Ferrari, Porches, Minis, paintings and cash worth £1million, often waiting until home owners were on holiday before striking.
Sayed Juied, 32, and Sadek Miah, 31, were jailed for six years each after admitting to raiding 21 muti-million pound homes in west London, Hertfordshire and Surrey
The gang were undeterred by security systems, officers said, instead viewing them as a sign a property was worth raiding.
If they found that valuables were locked in a safe inside, they would simply cut the safe out, before cracking it open later.
Officers first began hunting the group in July last year after a raid on a £2.6million house in Somerset Road, Wimbledon, next door to the Lawn Tennis Association.
Mohammed Alam, 26, was give five years. Police said the gang treated robbery as 'a profession', surveying properties before they struck
The raiders smashed in a back window before ransacking the property, taking keys to a £30,000 Porsche Cayenne and a £20,000 Mini Cooper, along with £13,000 of jewellery and electrical items.
The house was so badly damaged the owners also had to foot a £13,000 repair bill.
A week later the gang struck two neighbouring homesin Putney, including one £4.6million house, taking jewellery worth £38,700, and a Porsche Cayenne worth £75,000.
Continuing their all-night burglary spree, they hit another Putney home where they stole a personalised Ferrari worth £280,000, a matching Cayenne worth £130,000, and a painting worth nearly £50,000.
Jewellery worth £8,600 was taken along with £1,400 in foreign notes was taken from a house in Kingston Hill during another raid in July.
In another burglary in Kingston Hill last July, the back patio doors were forced open while the homeowners were away and the alarm system was smashed.
Jewellery worth £8,600 was taken along with £1,400 in foreign currency.
Three homes in Arthur Road, Wimbledon, were targeted between December 2013 and July last year, with damage caused to front doors and property worth £500 taken during one raid.
Police tracked the trio after staff at the All England Club, home to the Wimbledon tennis championships, caught their car on CCTV.
They passed the details to the Metropolitan Police, who found that the car had been rented by Alam, 26, from Unxbridge, who had used his real name.
That in turn led them to Juied, 32, and Miah, 31, both from Maida Vale, west London.
When police arrested the trio they found multiple Google searches on their computers on how to disable alarm systems and CCTV, and how to crack open safes.
The gang admitted conspiring to commit the burglaries, and were jailed for a total of 17 years at Kingston Crown Court on Wednesday.
Alam was given five years behind bars, while Juied and Miah were both given six-year prison terms.
Detective Sergeant Dan Mitchell, from Merton burglary team, said: 'They would conduct reconnaissance on big detached houses in really affluent neighbourhoods and then break in.
'They were quite an unusual team, they were not deterred at all by CCTV and alarm systems, that's how they thought somewhere was a worthwhile target.
'They would smash the alarm box as soon as they got in. They would go straight for the safe and try and take the whole safe out, the main think they wanted was cash.
'They were treating it as a job, a profession. They're the most professional team I have worked on.'
