He was charged by detectives from the Kent and Essex Serious Crime Directorate after being arrested on Wednesday.

His arrest came after Kent Police launched a large-scale manhunt when they linked three sex attacks - including one on a schoolgirl.
The first attack took place on June 29, 2012, when a 17-year-old girl was sexually assaulted in woodland close to the John Wesley Primary School in Singleton.
The second attack happened when a 47-year-old woman was out walking her dog on waste ground off Britannia Lane, Knights Park, on Thursday, September 6, 2012.
And the latest attack happened on the afternoon of Friday, August 2, when a 23-year-old female dog walker was on a wooded footpath off Bucksford Lane, near Singleton Lake.
Officers undertook a massive intelligence-gathering and public awareness campaign in the search for the attacker.
Over the course of the operation, DNA evidence was collected from more than 80 men across the borough.
Officers canvassed more than 5,000 homes in Singleton and South Ashford areas of the town, distributing leaflets featuring an efit image of the suspect and details of the attacks.
More than 100 schools, shops, dentists, and businesses were also visited, with posters placed in prominent locations, as well as parish council notice boards.
