Lohan Posts New Bail After SCRAM Set Off

Lindsay's Lawyer: Alcohol-monitoring anklet detected "small amount" of alcohol.

June 9, 2010— -- Lindsay Lohan is in hot water again -- this time over her court-ordered alcohol-monitoring ankle braclet.

According to People magazine, Lohan's ankle monitor sounded an alarm Sunday night while she attended an after-party for the MTV Movie Awards. It's unclear why the alarm was triggered, but typically authorities are alerted when the device is either tampered with or the person wearing it consumes alcohol.

Whatever the reason, it was enough for Beverly Hills Judge Marsha Revel to issue a bench warrant late Tuesday for Lohan's arrest, claiming the 23-year-old actress was "in violation for conditions on bail," according to US Weekly.

Because of the violation, Lohan's previous $100,000 bail has been revoked. The Los Angeles Times reported that the actress posted new bail of $200,000 to avoid being detained.

On Wednesday, Lohan's attorney and the prosecutor were back in court for a closed-door session with Revel. Lohan, who is due back in court July 6, was not required to appear.

After the hearing, Lohan's lawyer, Shawn Chapman Holley, told TMZ that Lohan's anklet device "indicated the presence of a small amount of alcohol on Sunday night."

"Having just received the report, I am not in a position to speak to its accuracy or validity; however, Ms. Lohan maintains that she has been in complete compliance with all of the terms of her probation and her bail," Holley said.

In messages posted on her Twitter account, Lohan also denied that she had done anything wrong and said the anklet, known as a SCRAM, or Secure Continuous Remote Alcohol Monitor, should have detected nothing.

"I did not violate anything at all," she tweeted. "My SCRAM wasn't set off ... It's physically impossible considering I've [done] nothing for it to go off. All of these false [reports] are absolutely wrong."

Lohan was fitted for the device May 24 after she failed to show up for a mandatory hearing on her probation related to an earlier DUI case.

Last month the actress used Twitter to send out a plea to French fashion powerhouse Chanel.

"can CHANEL please help me out by getting me some stickers to put on my scram bracelet so that i can at least wear a chic dress?! maybe!? x," she tweeted.

Could Lohan Trick Alcohol-Monitoring Bracelet?

Lohan's tweet came after a report in US Weekly magazine that the actress, who previously wore the bracelet in 2007, tried using a paper clip to jam the signal and perfume (which is high in alcohol content) to confuse the sensor.

The magazine said Lohan denied attempting both tactics. But she wouldn't be the first to try to bypass the bracelet.

Similar to a Breathalyzer, the bracelet detects alcohol, but instead of checking a person's breath, it takes samples from perspiration on the skin.

Brown said that of the 135,000 people who have worn the bracelet since 2004, she's never heard of someone effectively tampering with the device and evading detection, which would be a violation of the agreement offenders sign when the SCRAM is attached to their ankle.

But Vickers Cunningham, retired Texas District Court Judge and chief operating officer of Recovery Healthcare Corporation, a major SCRAM distributor, said that some offenders have attempted innovative strategies to bluff the booze detector.

Novices place cellophane or foil between the skin and the sensor.

"The more creative people have tried to simulate human skin by using baloney or salami or ham," he said. One even stuck chicken skin to his ankle.

But he said that the bracelets include several anti-tamper sensors.

It monitors temperature to make sure the bracelet stays attached to a human leg, it sounds an alarm if the strap is cut or stretched to the breaking point and has an infrared beam that measures the amount of light reflected by the skin.

The cellophane and foil trip the infrared alarm as they both reflect differently than skin. And he said those who use baloney, ham and other creative materials are caught because the bracelet can detect an obstruction and will alert authorities after eight hours of an obstruction.

Offenders Try to Bluff Bracelet

He said tactics like Lohan's alleged perfume-spraying strategy are known as attempts at "spiking the bracelet."

Offenders are told not to use perfume and other topical alcohol-based products around their ankles because it sends the reported alcohol level through the roof and masks any alcoholic beverages the person might have consumed.

But Cunningham said probation officers can tell when offenders spike the bracelets with gasoline, perfume and other substances and can send them before a judge to explain why they contaminated the sample.
