BANGALORE (Reuters) - Police have seized hundreds of pirated covers of the seventh and final book in the Harry Potter series, a city police official said on Monday.

Cash tills around the world have been ringing as the eagerly awaited last instalment of J.K. Rowling's boy wizard series looks set to become the fastest selling book ever.

Police said one man was arrested after officers raided a printing press, a storage depot and a private home in Bangalore.

They also found around 4,000 covers of books, including by Rowling and Indian-born British author Salman Rushdie, in the raids on Sunday.

"The covers look like originals," said Deputy Commissioner of Bangalore police Alok Kumar. "They were being transported to Chennai, Mumbai and Kolkata."

Police suspect some of the covers and pirated books were to be sent to neighbouring Sri Lanka as well.

In India, many bookstores have reported customers snapping up "Harry Potter and the Deathly Hallows" over the weekend, and media reports said publisher Bloomsbury and Indian distributor Penguin Books had begun an anti-piracy drive to coincide with its launch.

Pirated books by popular authors are often sold openly on the streets and in bookstores in India.

The Bangalore police estimate the value of the seized books and covers to be around to 4 million rupees.

"Depending on concrete information, we will organise similar raids," Kumar added.
