We report the results of a photometric and spectroscopic study of an eclipsing binary star in the field of the Delta Scuti variable AI~Vel. Time-series CCD photometry was performed allowing almost complete phase coverage. Our period search gave an orbital period of 0.9719d. The light curve is typical of short-period Algol stars and suggests the presence of phase-related increase of brightness (?=0.1-0.2) which can be due to mass transfer phenomena. Another possibility is the presence of a spotted region. Spectroscopic observation shows the Balmer Hα absorption line, typical of Algol systems with a transient or absent disc.
