Police have nabbed two alleged copper thieves at a northern Adelaide soccer club, amid a spree of thefts of copper wiring from lighting towers at amateur sporting clubs.

A 45-year-old man from Mawson Lakes and a 42-year-old woman from Elizabeth were arrested at the Salisbury Inter Soccer Club about 1:00am and charged with theft and property damage.

Officers said they were in possession of tools used to remove copper wiring, and an amount of wiring was located nearby.

Club president Bianca Simeoni said Salisbury Inter's venue was just the latest to be hit in an ongoing spree.

"A lot of clubs in the northern suburbs have been affected by this issue — I believe it's up to about 14 or 15 clubs now," she said.

"We've been contacted by another local club that had this issue happen to them two weeks ago that were hoping to train at our venue.

"We had been talking about the fact that it could happen to us."

No-one has been charged with stealing the other clubs' copper.

Other sports also hit

Copper wiring from lights at the nearby State Hockey Centre was stolen last month.

The centre's lights "should be fully functional again next week", Port Adelaide District Hockey Club president and former Kookaburra Dennis Meredith said.

Houses, construction sites and businesses in Adelaide, Murray Bridge and Whyalla have also been robbed of copper over the past month, according to SA Police.

Earlier this month South Australia's Office for Recreation and Sport sent out a warning to sporting clubs, urging the community to remain vigilant.

Night-time training sessions will be cancelled at the Salisbury Inter Soccer Club while the lights are repaired, which could take around a week.

Soccer training cancelled

Six senior teams were supposed to be training tonight ahead of games this Sunday, and a further 12 teams will be affected on Monday.

"Council have been in contact to say that they have cut all of the lighting so they can repair what's left," Ms Simeoni said.

"We're lucky I guess that they didn't get everything out, and hopefully we'll have the issue resolved sooner than other clubs."

She said while police had not drawn a link between this incident and earlier ones, the club thought the same people might be responsible for all the thefts.

"Hopefully this will put an end to this recurring issue that's been affecting soccer in our area," she said.

Police refused to grant either accused bail.

They are scheduled to face the Elizabeth Magistrates Court on Friday.

The copper price has risen about 6 per cent over the past six months, to $US2.92 per pound.
