Vikram Pratap Singh struck the all-important goal against the run of play in the 58th minute to lead the Arrows to their second win from nine matches.
It was Givson Moirangthem who set up the goal with a square pass from the edge of the box as the home team's defence was in a total disarray.
With the win, the Arrows snapped a hat-trick of losses but remained at the bottom of the table with seven points from nine matches.

Worse was in store for East Bengal as they were reduced to 10 players in the stoppage time following a double yellow to their Spanish forward Marcos Jeminez Espada.
Crespi had earlier squandered a chance in the 16th minute from captain Lalrindika Ralte's freekick as the home side dominated the proceedings in the first-half but without any goal.
