Spanish theme park operator Parques Reunidos could soon be boosted by a €33m (US$45.2m, £26.8m) investment package planned by owners and investors Arle Capital.

The injection would be used to further the firm’s growth in the European and US markets, however no details have been disclosed as to what projects the money will be used for.

The theme park group operates over 57 parks in almost a dozen countries, including Parque de Atracciones de Madrid and Movie Park in Germany.

The group also purchased Dutch theme park group Slagharen and US-based waterpark Noah’s Ark in 2012.

Parques Reunidos has attempted to expand its footprint in the United States of late, with an expansion project beginning in 2007.

Figures from the group’s website reveal that it closed the 2011 financial year with a turnover of around €543m (US$745.1m, £442.3m).

With a history dating back to 1967, Parques Reunidos is the second largest operator of leisure parks in Europe with 72 parks ranging from theme parks through to water and animal parks.
