Police in India have freed two men wrongly detained over recent bomb attacks on the holy city of Varanasi.
The two men were detained on the basis of photo fit pictures
Police detained the men saying that they fitted the description of two people suspected of planting a bomb in a shop which was later defused.
Police suspect militants fighting Indian rule were behind last week's blasts at a Hindu temple and a railway station which killed 14 people.
No group has claimed responsibility for the attacks.
The two men, who had been held in the city of Hardoi, about 80km from the state capital Lucknow, were freed after police found they had not been present in Varanasi on the day of the blasts.
They were selling sunglasses in Hardoi when they were detained.
The Uttar Pradesh police chief, Yashpal Singh, has offered a reward of 100,000 rupees ($2,250) for details that could lead to the arrest of the bombers.
Police said the photo-fit pictures of the two men had been drawn up from information given by the shopkeeper, who says he remembers they spoke poor Hindi.
Mr Singh told the BBC police had "enough evidence" to suggest the Lashkar-e-Toiba militant group was behind the explosions.
A wedding party took the brunt of the attack at Varanasi's famous Sankat Mochan temple.
Police say amateur video pictures of the wedding party have provided clues about "some suspects".
Nine people were killed in the temple attack and five at the city's Cantonment railway station.
Varanasi, also known as Benares, is about 670 km (415 miles) south-east of Delhi.
It is the religious capital of Hinduism and is usually packed with Indian pilgrims and foreign tourists.
