Lindsay Lohan ordered to testify at trial in London

Lindsay Lohan has been ordered to return to London later this month (May15) to testify in the trial of an obsessed fan accused of harassing her.

Daniel Voderwulbecke, 37, is accused of bombarding the Mean Girls star with texts and social media messages, and he is also facing allegations he clashed with a security guard outside a London theatre where she was appearing in a production of Speed-the-Plow last year (14).

During a hearing at Westminster Magistrates' Court this week (beg11May15), prosecutors argued against a request to put Lohan on the stand, with attorney Abigail Welsh declaring it is not "in the interests of justice" for the actress to face Voderwulbecke's lawyer.

However, Senior District Judge Howard Riddle disagreed with the prosecution and ordered Lohan to testify, telling the court, "The parties are aware that until today I had been greatly concerned that there was no obvious basis for calling Miss Lohan to give evidence, because no clearly identified issues had been put before me. However, I am satisfied from the information provided by the defence today that there is proper material on which to cross-examine."

Lohan will not have to face Voderwulbecke in court as she has been given permission to testify via video-link from another room in the court building.

Voderwulbecke denies three allegations of harassment without violence, two allegations of criminal damage, and assault by beating.

His trial kicks off on 28 May (15) - the day which marks Lohan's deadline to complete her community service order in the U.S.

She has to log 125 hours of volunteer work as part of her sentence relating to a 2012 reckless driving case by 28 May (15) after the bulk of her previous submissions were rejected by a judge. However, Lohan reportedly missed her first day of community service at a children's centre in Brooklyn, New York on Tuesday (12May14) due to problems with the paperwork.
