Park statue in Lahti, Finland

My photo of these 4 women was taken in Kirkkopuisto, on the edge of a beautiful little park near the centre of Lahti, Finland. I did some fairly extensive research on Google, but could not come up with a name of the statue, or the sculptor.

Maybe someone in Finland or Scandinavia can give me more details, as there was no plaque next to the sculpture. It was modern and beautifully crafted with a fountain flowing down the side of the sculpture to the base, set in a small square pond.
