Lindsay Lohan's alcohol level was up to 0.04 and her booze bracelet had been tampered with the day that it went off.
The actress' alcohol level ranged from 0.03 to 0.04 in the hours from midnight to 3am after the MTV Movie Awards when her SCRAM was triggered.
And preliminary reports suggest the alcohol detecting bracelet had been tampered with.
Linday's initial bail was revoked the day after the MTV Movie Awards when judge Marsha Revel deemed Lindsay had violated the terms of her bail by drinking.
"There was absolutely no doubt that Lindsay was drinking, and the report that the alcohol monitoring service provided to Judge Revel was very detailed and extremely reliable," a source told RadarOnline.com.
"The report also says that Lohan's SCRAM bracelet had indeed been tampered with, and this is one of the reasons that Judge Revel determined that Lindsay violated terms of her bail."
Can't wait for her July 6 court hearing on the matter! She might need to bring a pair of striped pyjamas with her!
