We have analyzed data on solar protons, neutrons, electrons, gamma-ray, optical and microwave emissions for the 1990 May 24 solar flare. Taking into account high energy neutron and gamma-ray observations, we have suggested two neutron injections occurred during the flare. These two injections are called f- (first) and s- (second). Two components of interacting protons correspondingly existed to produce these neutrons at the Sun. The flare gave also a rise to solar cosmic ray event, which was detected by the neutron monitor network and GOES satellites. Two components of protons were observed in the interplanetary medium (p- (prompt) and d- (delayed) components). A possible spectrum of the s-component of interacting protons coincided with injection spectrum of p-component of interplanetary protons. For this reason, s- and p- components of protons may be considered as different portions of a single population of accelerated particles in the solar corona. The net result is that three proton components (f-, p/s-, and d-) were accelerated during flare process developing from the Sun to the interplanetary medium.
