Police in the Indian city of Bangalore have seized a copy of the Koran they believe may have belonged to Mughal emperor Aurangzeb over 300 years ago.
The book was discovered after a raid on a hotel in the city. Police arrested a man who was trying to sell it and an antique painting for more than $1m.
The gold-embroidered Koran, written in Persian, has more than 1,000 pages. Experts are checking if a signature on the back belongs to Aurangzeb, who ruled India from 1658 to 1707.
Bangalore police have sent the Koran to the Archaeological Survey of India (ASI) to see if its experts can verify how old the book is and if markings found on it were made by the emperor.
