We have searched for microsecond bursts of emission from millisecond pulsars in the globular cluster M28 using the Parkes radio telescope .
We detected a total of 27 giant pulses from the known emitter PSR J1824 - 2452A .
At wavelengths around 20 cm the giant pulses are scatter-broadened to widths of around 2 \mu s and follow power-law statistics .
The pulses occur in two narrow phase-windows which correlate in phase with X-ray emission and trail the peaks of the integrated radio pulse-components .
Notably , the integrated radio emission at these phase windows has a steeper spectral index than other emission .
The giant pulses exhibit a high degree of polarization , with many being 100 % elliptically polarized .
Their position angles appear random .
Although the integrated emission of PSR J1824 - 2452A is relatively stable for the frequencies and bandwidths observed , the intensities of individual giant pulses vary considerably across our bands .
Two pulses were detected at both 2700 and 3500 MHz .
The narrower of the two pulses is 20 ns wide at 3500 MHz .
At 2700 MHz this pulse has an inferred brightness temperature at maximum of 5 \times 10 ^ { 37 } K. Our observations suggest the giant pulses of PSR J1824 - 2452A are generated in the same part of the magnetosphere as X-ray emission through a different emission process to that of ordinary pulses .
