Copper futures prices fell by Rs 1.30 to Rs 306.25 per kg today as speculators locked in gains after yesterday's gains.
Weak trend at the London Metal Exchange and subdued demand at domestic physical markets also weighed on the copper futures prices.
At the Multi Commodity Exchange, copper for delivery in most-active June contract drifted by Rs 1.30, or 0.42 per cent to Rs 306.25 per kg, in an open interest in 24,369 lots. It had gained 1.7 per cent at Rs 307.55 per kg in the previous session in line with global trends.
The metal for delivery in far-month August contract also fell by Rs 0.80, or 0.26 per cent to Rs 310.05 per kg, having an open interest in 8,051 lots.
Meanwhile, three-month delivery copper fell USD 190 to USD 6,090 per tonne, at the London Metal Exchange.
Analysts attributed the fall in copper futures to a weakening trend at the London Metal Exchange, where the metal edged lower after recording 2.7 per cent rally, and profit-booking by speculators.
Besides, subdued trend at domestic markets also put pressure, they added.
