Kate Beckinsale's alleged stalker has been arrested at Tampa Bay Comic Con over the weekend, where the actress was hosting a Q&A session.

The 45-year-old resident of Iowa, named Terry Lee Repp, was arrested at the convention on Saturday (29.07.17) on suspicion of stalking the 'Underworld' actress, who was scheduled to make an appearance at the event later that day.

Terry was booked in jail that morning on a $5 000 (R65 788) bond after he turned up at the Tampa Bay Convention Centre where the event was being held a few hours before the 44-year-old beauty took to the stage for her Q&A session.

In a police report filed after the arrest, officials say Terry "has a history of following and harassing [Beckinsale] and came to Tampa in an effort to continue the harassing behaviour."

The statement reads: "Repp made physical contact with the victim during an event in Salt Lake City, Utah in 2016. During this encounter, Repp touched the victim's back and made a statement to the victim in reference to stabbing her.

"In a continuing effort to harass the victim, Repp also traveled to Houston, Texas in 2016, where [Beckinsale] was attending an event. Repp was detained by the Houston Police Department and trespassed from the event. 

"Repp appears to have an irrational obsession with [Beckinsale] and has traveled across the country in an effort to harass her. Repp's actions caused the victim substantial emotional distress and caused her to fear for her safety. Repp has been charged with stalking and was booked into Orient Road Jail."

According to TMZ.com, a Florida judge called for Terry's misdemeanour stalking charge to be upgraded to a felony after claiming his alleged offence qualifies as "aggravated stalking", although the charge has not yet officially been upgraded.

The 'Love & Friendship' actress postponed her Q&A for several hours after the arrest as she headed to the police station to file a report, but made her scheduled appearance later in the day.
