Applied DNA Sciences Recovers SigNature DNA From Stolen Cash

STONY BROOK, NY,--(Marketwire - May 21, 2009) - Applied DNA Sciences, Inc. (OTCBB: APDN), a provider of DNA-based security solutions, announced that it has successfully authenticated SigNature® DNA on stolen bank notes received from the UK Police, assisting them in the prosecution of the alleged perpetrators.

Dr. James Hayward, CEO of APDN, has been in the UK meeting with law enforcement groups to demonstrate the SigNature DNA authentication process.

"DNA provides a forensic trail of evidence linking the criminal to the crime, and DNA authentication supports the enforcement programs of the various law enforcement groups," stated Dr. Hayward.

APDN completed the DNA analyses in its new Authentication Laboratory in Yorkshire. The bank notes recovered by the UK Police and submitted to APDN for forensic authentication appeared to have been washed multiple times by the criminals using harsh chemicals, in an attempt to remove the dye that stained the cash during the robbery.

SigNature DNA resisted removal and was still readily detectable using APDN's proprietary methods. APDN can supply an unlimited number of unique DNA codes enabling the unequivocal authentication of bank notes and other marked items. The same DNA markers detected on the recovered bank notes were also detected on personal items belonging to the suspects in the investigation.

Tony Benson, Risk Director, Loomis UK, stated, "This is the first time SigNature DNA evidence has been presented to help prosecute and ultimately convict offenders in the UK. We hope this evidence will serve as a warning to other potential criminals that they will be successfully prosecuted if SigNature DNA is found on them."

Loomis UK, a cash-handling company that moves over £150 billion in cash annually, uses APDN's SigNature DNA to protect its cash boxes. SigNature DNA is automatically sprayed onto the enclosed currency along with an intense dye whenever a Loomis Cash Box is disturbed. Any tampering with the cash-in-transit boxes will result in both the money and offenders being contaminated. SigNature DNA can forensically link an offender with an individual crime scene, meaning they cannot deny their involvement.

"As the conviction rate for offences involving SigNature DNA becomes known, the message for would-be robbers will become increasingly clear: if you commit these offenses you will be caught, prosecuted and sent to prison," continued Tony Benson, Loomis UK.
