SEVEN cars were broken into while a football team were training on the pitch at Feltham Community College.
Of the 12 cars in the parking lot, more than half had their windows smashed and valuables such as wallets, phones, and satnav taken, last Tuesday.
The players from Cranford are appalled by the lack of security and poor lighting which has paved the way for criminals to easily break in.
Darren Lalli, 28, found his windows smashed and cash stolen from his car. He said: "This is the first time it happened to me and I am not happy at all.
"This happened five years ago and everyone complained and nothing really happened but after a few occasions we started to get someone (patrolling).
"But for a long time now there are no lights in the car park and noone patrolling the place, which we were promised when we started paying more after the new pitch."
The 18-man squad had used the grounds for nearly 10 years for practice and matches, but did not return this week.
Another team member, Lawrence D'Lima, of Cranford, added: "We are local residents playing football and training in Feltham for 10 years. We know Feltham is renowned for car thefts and other petty crimes but within the sports complex there is no security and lighting at the school and they are supposed to have someone patrolling the car park. People do not feel confident about policing or security at the college."
The college has denied complaints over both the security and lighting and said this was the first break-in in seven months.
Ray Coleman, sports hall manager, said: "Since Sept 2012 there have been two members of staff working in the evening at the sports complex; one in the office/sports hall and one who oversees the outside areas including the Astroturf and the car park. The lighting in the car park has been improved.
"There has been an increase in charges to reflect the improvement in the quality of the pitches and also the significant investment made."
Police confirmed several cars were broken into at Feltham Community College between 8pm and 10pm, on April 19.
Detective Inspector Neil John of Hounslow police said: "It would appear those responsible have targeted these unattended vehicles whilst the owners were playing sport on the nearby pitches.
"Increased patrols are being conducted in the area and motorists are strongly advised not to leave any valuables inside their cars."
Officers are aware this is not the first time thefts have been reported in the area. They are working with the college to prevent this type of offence from reoccurring.
CCTV cameras did not identify the offenders and police are appealing for witnesses who may have seen or heard anything.
