The man accused of a deadly shooting during a premiere of a Batman film at a cinema in Colorado, USA may be subject to a lie detector test, the judge overseeing the case has ruled.

Defendant James Holmes could also face being medicated for a narcoanalytic interview - drugs to lower the defendant's inhibition - if he pleads not guilty by reason of insanity.

Holmes, who has not yet entered a plea, faces multiple charges of first-degree murder and attempted murder in connection with the shooting rampage last July.
