We report the detection of 167 bursts from an active repeater, FRB 20240114A, using the upgraded Giant Metrewave Radio Telescope. The observations were carried out over a frequency range of 300-750 MHz, and on four different dates over a period of 6 months. Our analysis indicates that the fast radio bursts' emission properties are evolving, with both the median flux and emission rate of the bursts decreasing over time. The properties of the bursts also vary widely, with a wide range of intrinsic widths (0.246-39.364 ms), scattering timescales (0.004-28.289 ms), dispersion measures (524.07-533.56 pc cm^–3), and band occupancies (9-180 MHz). The distribution for the waiting time, t_wait, is bimodal, and follows a Weibull distribution, with a shape parameter k = 0.33; however, when the two distributions are fit separately, they follow a Weibull distribution with k = 0.63 for t_wait < 1 s, and a log-normal distribution with a width of σ = 1.28 for t_wait > 1 s. The isotropic energy distribution is seen to follow a log-normal distribution as well, with a width of σ = 0.83.
